Most friends judge each other like investments & never realize it. When someone stops being beneficial they stop wanting them as a friend.

All people hide the bad parts of their personalities & bad people do it better. Your enemies & friends will sound exactly the same when you're around, but who's really your friend?

It's everything: it's their interests, hobbies, & loves - it benefits people to change their personality for everyone they know.

It's so hard to get intelligent advice that it's usually not worth asking - most politicians know nothing of history, most musicians know nothing of music, & most people know nothing of life. Really intelligence is just admitting what you don't know.

Never think "no one could be that bad" - millions of people make their livings lying as a salesman & CEOs, so how bad is any other lie that makes them money?

Everyone's "friends" are there when it's fun, but will they disappear when you need them?

And finally, the most obvious advice of all that *no one* in history has ever listened to:

_______________Don't try to change people.
_______________If you argue you're telling them who to pretend to be.
_______________Don't waste five minutes.
_______________If they think you're useful they'll lie to you for 90 years.
