Rant rant

I have red hair. I have always had red hair. Why do people need to point this out to me? Today at the grocery store I was in a self check out and a random dud comes right up to me and says "wow, that looks like almost real red hair. How'd you get it so good?"   "Um, it is real hair"  then the guy keeps talking to me about it. I just ignored him. really dude, do you think I don't know what color the hair on my head is?
