My parents had no choice but to leave me home alone. From the time I was 12. My siblings were all grown and gone, my mom worked from 6:00 am till 4:30 pm and my dad travelled 5 days a week. They couldn't afford a babysitter, and quite frankly, felt I didn't need one.
I had to come home, do my homework, clean the kitchen, make my bed and start supper. We knew all my neighbors; if I did anything out of line I knew they would report me to my mom. My aunt and uncle lived 4 blocks away if anything happened, I was to go to their house.
During the summer, I had to have my chores done before my mom got home. They bought me a summer pass to the local water park, which was three miles away, and me and my cousin spent our summer there. We rode our bikes or skated there. I was allowed to have girlfriends over, as long as my parents knew who they were. Boys were not allowed at all.
I am thankful my parents didn't shelter me. They taught me basic safety rules and then trusted themselves and me. In no way do I feel my parents were "irresponsible" because they left me alone at home.
In fact, it made me a much more responsible teenager than most of my friends whose parents sheltered them their whole teenage life. I had the confidence to move into my own apartment at 17. At 19 I moved to the big city of New Orleans, and at 20 I moved to the big city of Atlanta. I knew the difference between right and wrong, safe and unsafe, and common sense usage.
