Dear Jennova, I think you should be most concerned that you don't have anything more pressing to be worried about

You can come as you are. Wear whatever you like. What to wear at work depends on where you'll be working.

Do you run? There was a thread around here once by somebody concerned that they never see anyone running in the city. They were worried about being considered a social outcast if they should ever commit this disgraceful act. Use the search function to find this person. I'm pretty sure you can make friends

Have fun,
Diem
PS Just because you're paranoid, it doesn't meant they aren't talking about you.
