I act very comfortable around most people, just being me and all, and ive been told it can come across as flirty, but i dont think ive ever intentionally flirted. I am also oblivious to people flirting with or hitting on me in any subtle way. ill go out with friends and theyll tell me at the end of the night how some guy was hitting on me all night and how come i turned him a cold shoulder, and ill be like "huh? what guy?"
