I'll talk to like-minded friends about specific, objective investment subjects.
Do you like the options trading platform at Schwab?
Gee, AAPL just got back to $500. Think it has upside from this level?
Did you hear that Bank X is offering a 2%, 2 year CD?
Etc.
We never talk about our net worth, lifestyle choices (to what extent we LBYM), incomes, or that sort of thing.
I especially try to stay away from gossip style discussions about others (real or imagined) who choose to live differently. I have zero interest in bantering with another LBYM person about the sad case of a third party who is a big spender.
