Not my favorite day

I invited a friend of Mster's to come over the other day so that her mom could run and pick up her siblings since the 2 of them were playing so well together. I went down to the basement a 1/2 later only to find that Mster and this girl had dumped our books onto the floor. We own a lot of books. I immediately called the girls mom (who had been long home but I told her to just leave her girl play for awhile) and said I'm sorry but Msters in BIG trouble.

I guilted Mster. I yelled. I did all things disciplinary and then I put Cster's law books back up and made Mster put all the other books up herself. She was a speedster and cleaned up faster than I thought imaginable. She thought it was the GREATEST mom and daughter activity ever. I only put the law books up because I was worried they would get wrecked if Mster attempted. The fall down probably wasn't any good for them. And I didn't want one to crash on her head while she was putting them back.

Cster came home and claimed the rest of the week a "no friend over week" except for the time I already agreed to babysit a friends kids who happen to be Mster's best friends. All seemed to be well.

Then another friend called me yesterday morning. She needed a place for her daughter to take her nap. I thought "well, a nap isn't having a friend over. I want to help. I should say yes). So I agreed.

The girl came over and played with Lster for 20 minutes until naptime. She slept and woke up but her parents weren't home yet so Mster and her went down into the basement to play. They were playing well and I let them be. Her dad finally came to pick her up 40 minutes later and they came upstairs. We had some things to do and left the house soon after only to arrive home in time for dinner and bed. Later that night I went downstairs to work on my computer and almost died of a heartattack. These 2 girls had transported hundreds and thousands of little rocks into the basement. A fully finished basement. I was so mad. Cster wasn't home and I almost went upstairs to wake Mster up to yell at her.

The next morning I talked to her about it without yelling. I told her she had preschool in the morning but that when she came home she would get lunch and need to head directly downstairs to clean up the rocks. That was over 3 hours ago. There has been tears. There has been yelling. There has been apologies. There has been whining. There has been hurt feelings and still NO ROCKS HAVE BEEN PICKED UP. Her friends mom offered to have her come over before dance class to play for a few minutes and take them both to dance. There has been no friends. There has been no dance class. There has been more tears. And still NO ROCKS HAVE BEEN PICKED UP.

The thing I find most frustrating about the whole situation is that Mster has dissapointed me twice. The first was trashing our basement. The second is her defiance in cleaning it up. What a crappy afternoon. I hate listening to her cry. I hate the whining. I hate telling her to get in the basement. I hate having to hear her cry that she "hates to be alone" and that "she wishes somebody would just come down and be with her". But I can't cave in.

If I go down there what will she do to my basement tomorrow?
