I'm planning to spend no time with the kids I'm watching while the parents are away.
Why would you ignore them the whole time their parents are gone?
I don't like babysitting. The kids are crazy and loud.
Children need to be cared for whether you like it or not. You cannot leave them unattended. They could get into a lot of trouble on their own and their parents would never trust you again.
I just hate watching over kids.
You took on the job of babysitting, so you should do the job properly. Don't put the kids in danger due to your selfishness.
