Just dealing with it all....

A couple days ago my sister in law asked if I could babysit her 3 youngest all day while she went out of town for the day. Several times in our conversation she mentioned this was going to be an all day trip. She dropped them off at 7 AM and left. After lunch the 2 year old started wheezing, the mom had said nothing about asthma so I called her. She said she had been suspecting he had it and has an appointment with his doctor. Later in the afternoon, about 4 o clock she called to check on him, see how he's doing. I asked when she planned to be back, she said they were stopping to get something to eat then doing a bit of shopping then they would be back.
Ok, I thought, that gives them about 3-4 hours so I planned on seeing them at about 7 o'clock.  I try to have all my children in bed by then so I thought it would work out well.
By 7 pm I had every one ready for bed, had all the in-laws things gathered up sitting by the door. My sil called about then and said "hey we just finished eating and we're going to shop now and then be on our way home". We live at least an hours drive away from all the big shopping centers. Any restaurants in that area are either super expensive or do not take that long to eat at. I supposed it all depends on how you eat too. I know they are out of work so I didn't think they'd go to an expensive place but who knows?
At about 10 pm they came and  got their children.
I know I was very warned that this trip would take all day but oh man, did they have to take half my night too?! I don't babysit this family much anymore, I'll just know for next time, not to say yes on school nights, or if I haven't been getting my sleep.

I used to babysit their older children, every other Saturday night she would call and say how she NEVER gets to go out, could I babysit for a few hours? I didn't have anywhere to go, she played my stupid sympathy card and it worked. My husbands other sister was calling me the other, every other Saturday night, saying the same thing. Meanwhile I didn't have enough $ to grocery shop, let alone just go out. So I said "sure, bring them over". This went on for about 5 weeks, then I started telling them I was already tending someone else's children...
