Babysitting for the weekend: friend wants to pay $75
I have a friend that has two kids, 1 YR & 3 YR and a dog. She asked me to watch her children from Friday morning till Sunday night. She's going out of town for a funeral, and she doesn't really trust many people with her kids, so I agreed and took the weekend off from work for "personal reasons".
So last night we were talking about how much she would pay me and she said $75 and I know that is dirt cheap because I asked around and most sitters charge $100-$200 for an overnight weekend. I don't know how to bring this up to her, how do I say it?
I'm losing money by not going to work, I knew that already, but I can't do the weekend for $75-- I have school in September and bills to pay.
How should I tell her? The whole talking about money makes me uncomfortable, I usually try to avoid the subject as much as I can...
Help!
