My daughter is 23 months older than my son. She has always been the first to defend him, but she also thinks she can boss him around. Now that he is 12, he is starting to become a young man and we keep warning our daughter that one of these days, he is going to be bigger than you. On the way to the store about 2 months ago, they were play fighting in the back seat. She did something to get his goat, next thing we hear is " I'm sorry, go ahead, hit me back." So he did, only he missed her arm and hit her in the face. We had to have the talk about how it is not ok to hit girls now matter what. Our daughter jumped in to defend him and stated that she told him to hit her arm, he just has bad aim. That was the last time she started the play slap game. After our long talk about hitting, my husband and I had to laugh. She did too. The only one not laughing was our son who looked very pleased with himself.
I dread thinking about when they start dating. Not sure who is going to stop who from dating.
I know I didn't get many dates in HS as I had an older brother that was 6'3 and full of muscles on the football team. Not many guys were brave enough to face the whole football team. Sometimes older brothers suck. Other times they are nice to have around.
