It has happened to me a tons of times and i have always hate it. I think greeting somebody is a voluntary act and nobody should tell you to greet somebody if you don't want to because that makes it against your will and not voluntary. Im 17 now, im old enough to choose if i want to greet somebody or not, thats my choice and nobody cant force me to do otherwise. I know is bad manners,i know people will think i have no manners but thast my problem even though i dont really care if they think that, it dosent affect me, i dont live out of other people's opinions. So do you agree or not? Tell me what you think.
