Tired Tuesday!!!

Ok, so I am struggeling to find energy today! Don't know why really?
Could it be:
*I got up earlier than usual
*I didn't get a work out in
*I had MOPS today
*I let Sadie have a play-date
*I have been cleaning non-stop all day!
*Knowing I still have to make dinner
*Clean up after dinner
*Give baths
*Read bed time stories
*Say Good Nights

Why am I so tired? Is it just Tuesday?
