I'm not a very assertive person. Therefore, I'm the babysitter who every kid knows can easily be taken advantage of. It's not that I don't know how to yell... it's just that I honestly don't care if the kid does whatever they want. As long as they're safe, not making a mess I can't easily clean up, or they're not crying, then I'm happy.
It just doesn't seem worth the trouble arguing with kids. They like you so much more when you just do what they want, let them win at games, and compliment them on everything they do.
The only part about babysitting that makes me really uncomfortable is when the parents come home. This is usually what happens:
I don't know why they keep asking me to come back.
