It's Thursday

This morning, having a conversation about whether or not he need PE shoes today:

Ethan, looking confused: It's Thursday?
Me: Yes, It's Thursday.  It seems like it's only Wednesday because there was no school on Monday for the holiday, remember?
Ethan (Still looking a little confused):  Oh, yeah.  So I need my PE shoes because it's Thursday not Wednesday?
Me: Yes. 

Five minutes later:
Ethan: So, if it's Thursday, how come Nick doesn't have school?
Me: Um..... (oh, no...Nick had school yesterday, so it can't be Thursday....)  Because it's Wednesday?  (Shoot!)

Needless to say, Ethan was very confused, and I left to go get more coffee...
And yes, it's really Wednesday today, not Thursday.  It's a wonder my kids survive me somedays.
