I was a latch-key kid. I remember ca. 1975/76 I would come home from school and mom would leave the house key under the welcome mat. I was around 8 years old. Mom and dad both had to work, so I came home to an empty house. I would let myself in the house and call mom at work to let her know I came home safely. I would watch The Brady Bunch reruns, and mom would come home 30 minutes later. One day mom forgot to leave the key so I was locked out of the house. It just so happened that it rained that day. I cried.
