Flash is a crap nickname. If that's his real name, I bet he's a douche.
You're welcome. You mess up, you learn. Fix it and try to be better. I do the same things. But yeah, best thing is probably school and enjoy life as much as you can.
I know I'm not the best person to give advice or anything, but I also know Pepper worries all of the time when I'm doing anything dangerous. Not hard to imagine why your aunt flipped out. Her new nickname is going to be Mayday because you are so busted.
If you want a text with a code phrase if the planet is so messed up that we do need help, I can do that too. Because I also don't want you worrying that no one thinks you're good enough to help. When you are, and you have.
Not my choice. It's yours. You think it over and decide what you want.
