10. Texting while walking/driving/taking to someone
Needless to remind you what can possibly happen when you try to text
and do other activities side by side. Contrary to common belief
texting actually requires all your attention. Texting while talking to
someone face-to-face is rude. Moreover not only people get injured
owing to this reckless habit but even die. We often come across
stories of such selfishly reckless drivers who were busy texting and
had jeopardised his own life added to that of the passengers.

9. Talking loudly in public transportation
Have some pity over your fellow commuters, and either learn to speak
softly or don't speak at all. Think of the poor souls who have had to
face their sh*tty bosses and supervisors, married people who've
quarrelled with their spouse, young lovers who are dealing with raw
heartbreaks, think of all these poor souls trapped with you in a
confined space, growing frustrated by every second. It may so happen
that you are one of those insane loudmouths who just don't know how to
turn the volume down. If this is the case, the most humane thing that
you can do is ask the person to call later or reassure him/her that
you'd give him a ring later.

8. Taking more space than necessary
Another habit you that you might be guilty of (unknowingly, of course)
is sitting in public like you owed the seat. Well, sorry to break your
self-centred bubble, but you don't own the place, which is why it
called 'public place' and not a 'private' one. One more reason why you
so often take more space than you need is because you don't like
sitting sandwiched between strangers. There are two very easy solution
to that – get over it or stand the f**k up!

7. Making lot of noises while you eat
For instant, smacking you lips while chewing or opening your mouth
while chewing. These habits are not just annoying but pretty
disgusting, so much so that people who have witnessed your grand
display of chewed food spurting out your mouth occasionally throughout
dinner would avoid going out with you unless forced.
.
6. Mind what you say
Critics call it, the degradation of modern language. Our conversation
is often full of phrases such as 'like', 'you know', 'but', 'actually'
to mention a few. It's a fairly common habit and most people are aware
of how dumb and unconvincing these methods of conversations are. One
needs to consciously change this habit. Personally I have recently
acquired the habit of saying 'you know' at the end of half conveyed
sentences and although the person standing in front of me nods
vigorously, I know 'they don't know'.
.
5. Mind your language
Do you use slangs a lot? When you are with friends riding a bus or a
metro, you'd tend to use slang that may come across as bad manners to
your fellow passengers. It'll give people the wrong impression of how
you have been raised and the kind of family you belong to. It may even
repulse a potential love interest who had been swooning over you for
some months until your language has put her/him off.

4. Trimming or filing nails in public
This is gross. Yet some people do it. There's no excuse to this one.
Simply, don't trim or file your nails in public for heaven's sake.
.
3. Cracking knuckles
To my shame, I must admit, I love doing this even in public. And
people usually stare at me. It's not only embarrassing but highly
annoying. How did I know that? I heard other people cracking knuckles
in public. And some of them even brag about being able to make noises
with their figures. One of my friends recently confessed that he use
to love cracking knuckles twice every hour. When he got to high school
his teachers would throw his angry looks and once a girl turned around
and told him that it sounds nasty.
.
2. Blowing your gum
Chewing gum or blowing gum can be a really bad idea, especially in
public. Some people simply can't resist the idea of blowing out the
gum. Avoid blowing gum, or better, chewing gum altogether in public
setting, like school, work, bus, restaurant et al. But if your life is
absolutely incompletely without chewing the gum, then kindly do it in
your home.
.
1. Biting nails
This is one intolerable nasty little bad manner. The basic reason is
the saliva that envelopes the finger and added to which it ruins the
shape of the nail.

Digging of nose, picking of teeth with fingers and handling of joystick

Picking the nose. A very embarrassing thing to do in public, especially when you re in the act and you turn your head only to find a pretty damsel you got eyes for starring at you the whole time!
