Ha! I was the same! I used to go to my mom´s office 2 or 3 times a week after school because there was no one to take care of me, so I would just help out other people in the office to do small tasks or at some point they would even just invent tasks for me to stay occupied :P
I think you are doing a great job with your children, teaching them about how real life is going to be when they grow up :)
Awe thank u so much! I just dont want them to be a burden to others and it has to start as young as they are now.
