What are some jobs for a 13 year old to do over the summer?

Well you already babysit.....what about walking dogs, planting flowers or watering lawns for neighbors, anyone you know need a fence painted or need their windows washed? Do your parents need the garage or basement cleaned out? Maybe you can do it and then have a yard sale. You could wash people's (neighbor's) car's or get a paper route. Clean people's pools......maybe if you can keep a bunch of different things like this going all summer, you can keep the cash coming in. I know when I was thirteen, I went to a local hair salon and they let me sweep up hair and shampoo and do other things like get their lunch, etc.
