Oh no!

So, just a funny story to tell...
On thurs morning I got the girls all ready for school, they were just leaving for the bus when Kaden tells me that her tummy hurts. I told her that it must not hurt that bad since she was just now mentioning it. I told her to try going to school and if it didn't get better, tell her teacher and go to the nurse. Kaden told me that her teacher never sends anyone to the nurse unless they feel warm. So I told her "tell your teacher that your tummy hurts and you feel like you might throw up because then she I'll send you to the nurse for sure because no teacher wants a kid in class that is going to throw up."
Well around noon, the school is calling me. I answer it and the school nurse has Brylie in her office because she told her teacher that she felt like she was going to throw up!! I said oh really...ok I will come get her.
Brylie came home and had to lay in her bed all day since she was "sick". Brylie wasn't even really by us when i was telling Kaden that in the morning. Brylie is sneaky though and a little smart for her own good.
She never ended up throwing up....imagine that. I hope she doesn't use this excuse all the time. I tried making coming home sick- not fun at all so that she won't want to try it again! What have I gotten myself into?
