There is zero reason to tell close personal friend that you have more than $1M in assets unless your friend have comparable assets. People are jealous and telling somebody that you have much higher salary (especially if are in the same industry) or you have a lot of assets is the sure way to destroy friendship.

Well, there are other ways to infer it if you hang out with someone on a regular basis, eg. if they say "I'll just work for another 5 years and retire", or if they own 3 homes in the Bay Area and aren't complaining about mortgage payments, or if you do an anonymous net-worth survey among many of your friends and see that some of the top rows are over $1M.
