Can I tell an elderly person to gtfo?
Are you really gonna tell this person that?
Yeah. I don't want to talk with that old dude any more
It's mean to yell at people. You should learn to respect your elders.
Eh, I think old people are annoying and don't deserve my respect.
Don't you think you can stop talking to the man in a more acceptable manner? Maybe you can just tell him you don't have time to talk.
