Me and my dirty hair

It snowed all day today, and it was really quite beautiful to watch the snow fall throughout the day. Close to three o'clock I got Collin and I bundled him up to go pick up Talin from school. Well, as we were heading outside, Tom called and said he would pick him up. I was a little bummed because I enjoy driving in the snow, especially freshly fallen snow. And a little worried, because Tom's little car does terrible in the snow. So I decided that since Collin and I were already bundled up we would play outside. I'm not very good at playing all the time. All I could see was snow that needed to be shoveled, so that's what I started to do, shovel snow. I know I probably shouldn't be doing that being six months pregnant and all, but sometimes I get frustrated by limitations and do things anyway.
Well all the neighbors seemed to be out shoveling as well, it was really quite social. My next door neighbor (not the naked one) started a friendly conversation about the weather and what not.
Then he asks me, "Didn't your hair use to be blonde?"
I reply with a yes.
Then he says, "So is this your natural color then?"
I tell him I'm actually a natural blonde, and I've dyed my hair this color.
His reply, "Why would you dye your hair that dirty color? You should have gone red, all the movie stars have red tints in their hair now, that looks really good. They say redheads have more fun."
What??? Did he really just call my hair dirty?? I was appalled. I've only talked to this man a handful of times with the occasional hi and how's your day, and he had the nerve to tell me my hair looked a dirty color?? My only reply was, "Oh, I thought blondes have more fun."
What??? Why can't I ever think up something witty on the spot, or put people in their place who are out of line. And why am I so upset about what some random neighbor thinks who obviously has no style or great opinion or class for that matter!
I went inside shortly after that. I didn't want my 'dirty' hair to offend any of the other neighbors.
