Were you a "latchkey" kid? I was.

My parents both worked. Rather than give us little tykes a house key(bad idea), they hid a key outside...most of the time. When that happened, my younger brother and I would simply play outside until my folks returned.

For me, that fostered a feeling of content when I'm alone. That doesn't mean that I'm anti-social, but sometimes I do look forward to having no one around and I can get things done at my own pace.

Anyone else experience this growing up?
