What would you Mostly Regret in your Life ? Stuff you never want or want to do! What would you regret most in life ?

I regret not buying enough tennis balls to fill my friend/date to the prom locker. I don't regret anything else.

Being born, I hate my life and muse

Stuff.

If i were never there for my friends and just stayed hidden from all humanity

What WOULD I mostly regret in my life?

This needs conditions. In what universe?

Or did you mean "What do you mostly regret in your life?"

In which case, I am going to shut up and leave this question immediately.
