Advice Anyone?

Today I came home from the grocery store to find my 10 year old slumped over with misery in his voice and face...he left his brand new bike at school on Thursday and only remembered it today. When he ran down to find it...it was gone. We live in a lovely little neighbourhood, so it is possible that someone locked it up in the school for safe keeping over the weekend, but in all likelihood, it has been stolen. We prayed about it. We have never bought such a nice bike for our kids- for many hard core mountain bikers around here, it is not an expensive bike, but for us it was a big purchase. The plan was to pass it down through the other two boys, as it is a good quality one. Therefore, I mentioned to K that he might have to replace it with his own money. He quickly replied that he had enough in his bank account. That is true- we have put birthday cheques from his grandparents in there for years now, and it has added up. He never touches it and had no plans for it, so in a way, it is almost too easy of a solution. See, this is our sweet, forgetful, absentminded child. I am a little that way sometimes too, so I feel for him, but it is getting to be a problem in his day to day life...no homework comes home from school, no lunch containers return, his backpack is left at friends houses, he forgets to do chores I give him, etc. Today he walked to our neighbourhood corner store to post a LOST BIKE sign he made, and got half way there before he realized that he forgot the sign!!! So, I want this to be a little more of a hardship for him and wonder if running out and buying another one with his money will make enough of an impact on him in the present so that he hopefully makes more of an effort to mend his forgetful ways. He is not being bad or defiant in my eyes, so it is not like we want to punish him. I dunno, maybe it is just a long phase...what do you think? What would you do? The Skip and I haven't had a chance to talk about it yet tonight- maybe you can give us some food for thought.
