Some random bits of wisdom I have just learned.

For a 24 year old, being friends with teenagers (18 and 19 years old) is a very bad idea. Especially ones that have no cars and depend on you to drive them places. Or ones that have no semblance of education. Or ones that convince you to lend them money to bail their boyfriends out of jail and then never bother to pay you back. They are, in general, stupid and not worth wasting your time on, and your generosity and naivete will only blow up in your face when you dare to wonder if perhaps one of them is using you because it's been three months, and you've seen neither hide nor hair of your $100. Because of course the one you confided in will blab to the one who owes you money. And she'll call you out in the most melodramatic of teen angst bullshit that you realize you outgrew around the time you had your first date.

Food for thought. Not that it ever happened to me, of course. I'm way too intelligent and way too good of a judge of character to get into situations like that!
