Skinned Knees

My baby skinned her knees this morning. Both of them. It's not the skinned knees that really got to me, she is going to get those... I realize that. What got to me was that I had to leave her at school with her skinned knees. She fell when we were walking into school this morning...so I had to pick her up, carry her into the class, clean and bandage her wounds and then leave her there. Don't get me wrong, she was just fine. I, however, was not. I wanted to wrap her in my arms and hold her there all day. I wanted to be there in case there was some pain later.
I know that you can't always be there when your children hurt, but it doesn't mean that I don't want to be.
