My parents left me home alone when I was 10 years old. I was also responsible for my younger sister who was 5 years old. They had a family buisness and would take my older siblings to help them and left me home with my sister to take care of her and the home responsibilities.
I had to clean the house and also have dinner cooked and ready for them when they got home at 6pm. I had a big family, there was 8 of us total. ANd, my step-dad was stict about making sure the house was cleaned and dinner had to be ready, table set, salad with viniger and oil, sweet tea, cranberry sauce, all had to be done the way he expected it.
I never thought much different when I was a kid about the rules. I even from time to time walked a mile to the grocery store to pick up things if we ran out. And, I had to take my younger sister with me. I look back and am shocked that my parents had me do that, but we were also raised with loads of reponsibility and grew up fast. I didn't have much of a childhood.
But, now I am a mom and i have an 8 year old who is not anything like when I was a kid. Even though I raise her to be independant, she is far from ready to be left home alone.
Keep in mind, had the stove caught on fire when I was a kid, the house would have burned down and I may not have survived. Even though I SEEMED responsibile enough to do those things I did, there are lots of safty things I was not mature minded enough to handle. Kids are kids - don't let them fool you. As much as we'd like to think they can handle themselfs in many things, truth is - when it comes down to it, they Can't!
Be patient - We are the parents and are ultimatly responsible for our kids. Don't leave your kids home to young to make your life easier. Yes, maybe you may get lucky and nothing will happen. But, then again, what if a nosey neighbor calls the cops or social services, or comes by and rapes and/or kills your child. It has happened and you are not invincible to it happening to you. Once it does, you cant take it back.
