In 2 years, we all from here will be rich! In that moment life will be very funny (from the point of view of friendship): in that time, you will receive calls from "friends" that suddenly remember you. They will say:
Hey my man! We should see each other often. We have SO MUCH things in common!
But at the end, they remember that they need some money… Do you know these kinds of friends?
But as you say: "Actually it's fine to trust people." Maybe too funny, in certain circumstances... I say.
