Its just human nature for people to notice/comment on any characteristic that is non-standard. Skinny people get lots of comments, as do people who are tall ,short, bald, have a large nose, pregnant, etc. When I was younger, any male with long hair heard a lot of comments, mostly derogatory.

My oldest son has a prominent birthmark on his forehead. He is always getting asked about it. He has learned to accept the fact that it will be mentioned.
