I had to explain to him that unfortunately not everyone respects other people's property, making it important that we put our things away when we are through with them so that those individuals aren't tempted by our nice things and do something they shouldn't. The hardest part for me was not running out and buying him another scooter and helmet. I originally thought that the small wheels on that type of scooter made them a bit dangerous, and told him that I would not buy him one and if he wanted a scooter like that, then he would have to spend his own money to purchase one. Well, he saved his birthday money and some allowance money and bought himself the red RAZOR scooter you see above. I was proud of him for saving his money for something that he wanted, and am now hurting that it was stolen from him.
Luckily, my mother-in-law bought him a nice skating helmet for the holidays, so he has another helmet to use when he rides his bike or skateboard (yes, my family all wear helmets when we do not have two feet on the ground). He hasn't yet said whether or not he will buy himself another scooter.
Unfortunately, Jake had to learn about stealing the hard way. Sometimes I hate natural consequences, but I'm sure he learned his lesson and will think twice before leaving anything out for those tempted individuals who were not taught the Golden Rule.
