I figure the less information you know, the better. Nosy people just need inquire.
Seeing as how I hate most people, you probably won't like me and I probably won't like you.
I'm not a nice person, and I don't sugarcoat things. If you have easily hurt feelings, it's best you stay away.
If you're not an a*****e, then go ahead and say hi. You never know what might happen.
