My son broke our air conditioner while climbing on it

I definitely agree that the joys of parenthood outweigh the hard times, but that does not mean that everyday is enjoyable. I have three little ones, and I love them dearly. My oldest is seven, and he is just starting to get to the age where he has a bit more freedom but not as much as he wants. He and I have had some pretty heated discussions lately, and I hope that he understands why I have certain rules for him. One of those rules is not climbing all over everything in the living room. I do not mind if he plays in there, but I told him not to climb on things like the air conditioner and my end tables. Well, he decided that he wanted to climb up on the air conditioner and jump off. I found out later that he had been doing that for a few weeks whenever I would leave the room. One day, I heard a crash in the living room, and I ran to see what was wrong. The air conditioner had fallen forward out of the window and onto the living room floor. The entire front of it was broken in pieces, and it has not worked right ever since. My son felt really bad, and I think that he learned his lesson the hard way. He told me that he was about to jump off the air conditioner like usual when the entire thing just came crashing down. I am not happy about what happened, but I think he learned his lesson. My husband has been looking at air conditioners to see if he can find a good deal on a new one.
