My nephew was always around the garage.I thought it was funny when he lost my brothers tools.Not so funny when mine came up missing.He will use your floor jack to lift up his car.and be prepared over the years to go searching for your tools when you need them.Also parents of the other 4 yr olds coming to you because your son has taken all their bikes apart.!My nephew is 16 now and has more tool than his dad and I put together.Probably our old ones we gave up on finding and just went and bought new.
