I'm happy your son is home. I hope he has a speedy recovery!
Some cultural differences. We call 8 ball pool. We call 9 ball 9 ball, but I've never heard anyone say "Do you want to shoot some 8 ball?". We don't say pot when we hit a ball in we say sink. We "sink the eight ball" or " you sunk the 9". We say rack, break, stripes, solids, and scratch (sinking the cue ball). I used to play a fair bit as a teen, but it was usually more about smoking, drinking, gambling, and thinking I looked cool. I'd play again if I had access to tables that weren't smokey and filled with drunks. Oh how times change. It would be nice to have a club that took it seriously, but the tables I can play are at seedy bars and bowling alleys.
