I'd add also that learning to hear someone tell you no and not taking it to heart and getting on with your life. So many people walk through life being afraid of hearing someone reply "no" to them, like its some existential rejection of them and that stops them from doing many things.
I'll make chit chat with anyone, and people who dont want to chat with are generally pretty explicit about saying they dont want to chat or don't have time, or pretty obviously implicit about it by not engaging or looking for ways out.
I feel that line of thinking can have some very grave consequences. My mind is swimming with intrusive thoughts half the time.
