Bug has a birthmark on the right side of his nose, kind of between his eye and the bridge. As a baby it was puffy and very dark red; it couldn't be missed. It started to show up about a week after he was born. At first we thought it was simply a scratch he had gotten from his fingernails being too long. Then it didn't go away and Hubby said he thought it looked like it might be a birthmark. Gradually it grew bigger to become about the size of a penny. The doctor said it would eventually fade and go away, which it has. People still comment on it but they don't have quite the same reaction to it as they did when he was younger.
When Monkey was around 3, he acquired a beauty mark on the right side of his nose. It is in the exact same spot as Bug's birthmark. The first time I saw it I mentioned it and said something along the lines of, hey, you have a beauty mark in the same spot as Bug's birthmark! He asked what a birthmark was and thought it was awesome that he and his brother were "twins".
Fast forward a few years.
The other day in the car Sunshine mentions that it looks like Bug has a new freckle. Bug doesn't have freckles and the spot she saw it was on the underside of his arm, not the spot where you would suddenly start to acquire freckles. I told her it probably wasn't a freckle but a beauty mark, and then this happened:
Monkey: I have a beauty mark just where Bug has one. We're twins.
Sunshine: Why does everyone say that Monkey and Bug look the same?
(Before I can answer)
Monkey: It's because we have blonde hair and we both have birthmarks on our noses in the same spot. (how convenient that his beauty mark turned into a birthmark)
Sunshine: That's not fair! Why do they both get one and I don't?!
Me: Really? Are you really getting upset about this?
Sunshine: What? Why do they look alike and I don't? It's not fair!
Me: I believe you do have a birthmark, don't you. In fact, don't you have two birthmarks?
Sunshine: Yes, but it's not the same.
Monkey: I want a birthmark too!
Sunshine: You already have a birthmark!
Monkey: No, it's a beauty mark! I want a birthmark! Why don't I have a birthmark too?!
Me: (Not believing that we are having a discussion much less an argument about this) Both of you be quiet and stop arguing. Let's play who's the quietest!
Monkey: NO! I hate who's the quietest. You know I'm not good at it. Let's play who's the loudest!
Me: I will turn this car around and we will go back home if you 2 don't stop arguing!
These are the arguments that no one tells you will happen. People may tell you they argue about ridiculous things, but you don't really know until you are in the midst of it. Driving. For 20 minutes. By yourself.
