What public behaviour is the most irritating to you in the place where you live. Написать почему люди ведут себя так

I just cannot stand when people litter on the streets. I think that they do that because they are kind of lazy to put their litter in a bin little bit far away from them. People should understand that this kind of behavior harms not only the neighbors but the environment too.

Also I’m irritated with people who crowd in the bus. Especially it drives me crazy in the winter when it too hot in the bus. They just block the doors and it’s too hard to get out of the bus when you need to. Also they are always trying to push me.
