Don't judge me, but I hate old people sometimes
I can't believe anyone would say that. Why on earth do you hate old people?
They are really annoying. They think they're hot stuff and they're always trying to teach me something I don't care about.
You shouldn't hate people due to their age.  The fact of the matter is, older people do have things to teach the younger generations.  You could benefit from their wisdom.
You're an old person aren't you?
Does my age really matter? You need to give older people more of a chance before deciding that you hate them. Also, don't discount the advice from older people who are much more experienced than you.
