Because I won't miss this mess.
Sure, I will miss the pitter-patter of tiny feet running up and down (and up and down) my hallway. I won't miss the perpetually dirty floors that nag me to mop them.
I will miss the slow summer mornings spent exploring the beach. I won't miss finding sand in every nook and cranny when we get home...and for days after.
I won't miss this mess - the milk on the floor, the marker on the walls, the what-the-heck on my shirt and the I-don't-even-want-to-know on the van floor.
I will miss the tiny curious hands and sugary kisses and soft voices that tell me
"Mom, you're amazing. NOT as amazing as God, but still pretty amazing."
There are at least a million things I will most definitely miss, but this mess ain't one of them.
