Three pieces of advice for today:
1. Be kind. At least try. The effort is worth it, I hear.
2. Ask questions about anything that doesn't make sense. And don't settle for ridiculous, stupid, non-contextual, or incomplete answers. Especially if they're a combination of all four.
3. If you're going into a public restroom - or really, any restroom that's not in your own home - and there's a possibility that you'll need toilet paper while you're in that restroom, then check immediately upon entering to make sure that it has (unused) toilet paper. It is a good thing to be certain of at the beginning, rather than the end.
Mazel tov, world. Be brave.
