There she goes again, asking you for a HUGE favor after she has said really horrible things to you! If it's such a small thing that there can be no reason for you to say no, why doesn't she off-load her four kids on someone else?!!!

Maybe if you start saying no, because of the way they treat you, they will stop treating you that way. They will have to, or they will never be able to take some time off. Unless you think they are nuts enough to stop letting you see their kids altogether...

Make me compliant and sweet and capable of only the nicest, kindest words, even to those who deploy the most insulting and demeaning words toward me.

You are this kind of person!

An extended vacation might be just the thing for you. Come to me!!! The most boring place in the world, and it's swell.
