Fun as usual, but the whole "100 friends" cliche never made any sense to me. I think social scientists say that you can only have about 6 or so close relationships that are actually meaningful, and the more people you expose yourself too superficially for the purpose of being "friends", the more risks you take. There's a reason why aphorisms like "Don't be surety for a stanger" or even your "friend" exist.
Takes a long time to know who you can actually trust, and even then, people change over time.
