I’m nearly 40 and the world they are facing is so different to what I experienced that I don’t know if any advice I could give would even make sense.
Don’t suffer fools, I guess. Life is too short to put up with people who don’t, won’t or can’t respect you.

Because I don’t know about the Clone spell.
