coming home early

J went hiking/camping this weekend with his scout troop. They were supposed to be home late tomorrow afternoon. He called about an hour ago saying they were on their way home. He said they decided to come home a day early. Then he mentions he fell and hurt his knee. (he said they had decided this before he got hurt, but it makes me wonder) The opposite one from the one he hurt at camp a few years ago. He doesn't think he needs to go to the ER, I'll look at it to know for sure. We have an abundance of knee braces, (2, but he only needs one) and he still has his crutches so he'll be able to stay off of it for a few days if he needs to. I thought R and I would have a quite night just the 2 of us, with P at work and S spending the night with Aunt Jul. I guess not. update- 8:30 PM- he's home and the knee looks a little swollen, he has a brace on it and is icing it, I felt around and didn't feel any movement like if he broke his knee cap. We'll see how he does the rest of the night and tomorrow morning, then we can decide if we need to take him to the doctor's office. Rest and ice it is my prescription for him. Dr. MOM that I am. HA!
