I swear I am getting so tired of seeing kids that have no business being out and about alone being out alone. We live on a fairly busy street and I can't tell you how many times I have seen a 4 or 5 year old riding their bike up and down the sidewalk alone with no parents in sight. The neighbors had their 2 year old out by herself one day and I watched her walk into the backyard. Her mom was in the house and didn't see her walk off. She was yelling and running around frantically looking for her. She could have been in the road for goodness sakes!
