What is the worst habit people have?

For me, I got disgusted when people don't flush after using the toilet or they didn't wash their hands. eeeewww.

I dislike people who are pompous, self-opinionated and who like to hear the sound of their own voices.Such persons are intolerant of others and get angry when their opinion is turned down.I keep such people at bay and discourage their friendship with me.

I don't like people who talk with the finger pointing at you.

I am with you! I hate to see people or hear people talk with a mouth full of food. I also don't like it when people chew their food and smack their lips.Yuck!

I hate it, and it also grosses me out, when people lick their fingers in front of me when they are done eating. I went to dinner with a friend and after she had eaten something that required picking it up with her hands, she licked her fingers. And she didn't just lick them, she made a smacking noise after each finger. It is so gross and I think it is one of the worst manner faux paus ever to be committed. It's just nasty. Use a napkin!

Hmmm,I think for me,I can not endure the one who promise to you for one thing but do another one ...
It's named double-dealer ...
So,i will get away from the man who has this kind of habit and never treat them as my good friends...

I hate when people pick their nose, oh gross..

I have something that tops that by far. People that pick their nose and then eat their boogers. Nasty! I want to vomit when I see people do that. I have seen on more than one occasion a man in the next car pick his nose, really get up in there and pull out a big booger and then suck it off his finger. Then they like gnaw on it. Yuck! Then they probably go home and kiss their wife or girlfriend who has no idea! I would rather have someone talk with food in their mouth any day!
