Okay, first of all, would everyone just learn to say the words "thank you", "you're welcome" "excuse me" "sorry" and "have a nice day"!
If everyone just made sure they used those words every day, people would be so much happier. I can not believe how rude people are. Stop being so god damn selfish and start looking out for other people's feelings. When you bump into someone, say excuse me or sorry. Appologize when you're wrong, better yet, don't be wrong. When someong does something for you, say thank you. When some one says thank you, say you're welcome. Learn it people. And be nice. Just cause you woke up with a bug up your ass doesn't mean you have to make it a wrotten day for everyone else. Have some consideration. Have some manners, cause once you're nice to someone, it is much more likely that they will be nice right back to you and be more willing to do you favors. Smarten the hell up.
