1. People assuming you're a bitch. I'm a nice person. Honest
2. People not warming to you straight away because they think you're mean.
3. People assuming you're always pissed off. "Are you ok?" "What's the matter?" "Are you not enjoying yourself?" Can I live!
4. People saying "Smile" when you're walking down the street minding your own business. I wish I was making this up.
