I turned five in a hot tub

The first part of this story begins in the summer a few weeks ago.
Place- swimming pool with a hot tub
Time- 3:20 pm
Rule- You have to be 5 to get in the hot tub.

Shane: " Lucy I guess your 5 now" {kind of jokingly kind of not}
She did not pass for 5.......surprised?
And she was not very happy about it.

Fast Forward 2 weeks ahead to the first day of school.

Lucy: I wanna go to school.
Me: You can't your not quite big enough to go to school with the kids
Lucy: I am BIG seeeeee. { as she looks down at her tiny frame inspecting herself}
Me: I know you are getting big but you have to be 5
Lucy: I am 5
Me: No your not your 3.
Lucy: NO uh ah. uh ah.
Me: So when did you turn 5.
Lucy: In the HOT TUB. {it took me a while to figure out where this crazy idea was coming from}
Me: Well I guess your 3 again.
Lucy: I don't like 3.

But she is stuck being 3.
And it is just me and her for while.
Running the house.
It's a good thing.
