Spilled Lemonade

So, Maggie woke us in the middle of the night the other night, and said she was all wet.  We changed her, removed her sheets, and sent her back to bed.  We knew she peed the bed, but she had other ideas.

In the morning, she was telling us how her bed was all wet.  We said, "Yeah, because you peed in it!"  She said no, she spilled.  WHAT?  So here is her story that she is sticking to:
She got up in the night and went to the kitchen.  She found a lemonade on the counter, and she was thirsty.  It was a lemonade from Sams Club.  She took it back to bed with her, and laid down and tried to drink it, and the lid came off, and it spilled all over her panties and nightgown, and then on her bed. 

Haha.  We tried to tell her that we did not have any Sams Club lemonade that day, and that she must have just had an accident.  But she is sticking to her version of the story.
