I HATE IT WHEN PEOPLE PASS BY WITHOUT SAYING "HI" OR "HEY".

I HATE IT EVEN MORE WHEN THEY SHOUT AN EMOTIONLESS "ON YOUR LEFT".

Just say hi or how's it going or nice day, huh? Don't say on your left or anything like that cuz it sounds snobby and mean. I'm always annoyed when people do this. It's like they can't greet you or say something nice. They just want you get out of the way for them.

My two cents.
