Being rude back is just a road I try not to take. I would handle it in one of these two ways:
A: She's a beautiful little girl! What's fun to do, is, when people ask you something like, "Where did you get her?" You simply ask "Why do you ask?" They will stutter and stammer.....they can't just say yes or no...so it kinda makes them uncomfortable! Then you can watch them squirm......without being rude like they are!
B: My kids look totally different. Nick is nearly 6 feet tall and slender, with dark hair and eyes, and Joe is short and has hazel eyes and sandy blonde hair. I get teased alot, but it doesn't bother me a bit...I just say...."Must have been the milkman....or was it the mail man.....!"
Laughter is the best medicine!
