Do you think I should not respect my the parent's wishes as a babysitter?
Are you sure about this? Why won't you respect their wishes?
I don't feel like following their rules.
Maybe babysitting isn't your thing. It's not cool to ignore the wishes of the parents if you are babysitting their kid.
Nah, I'm going to do what I want. I don't need to babysit anymore.
I think as long as you live under your parents' roof, it might be a situation where you have no choice. Sure, you can refuse, but at the end of the day, they will just hire someone else to do it and you will have to be at home with this babysitter you don't even know. It will be awkward and all that, so it's probably more relaxing and less awkward if you watch over the baby yourself.
