Time off

I've not been alone like this in a long time.
Barely an hour ago there were 2 laundry baskets full of kids clothes, 2 sleeping bags, pillows and blankets, stuffed animals, shoes, rain boots and slickers, back packs full of toys, and glitter strewn about my living room.
Now it's gone, all of it.
All of their trappings loaded into their car.
Even the glitter has been vacuumed up.
The house is so quiet that it is buzzing.
The dog is asleep on the back of the couch.
It is just starting to drizzle outside.
My husband is on his way home from the Northwoods. He'll be home in 7 hours.
My grandson is at school and my granddaughter was just picked up by her mother (my daughter).
The grand kids have been staying with me for the last week while their parents were on vacation.
My daughter wondered aloud wouldn't it be nice to have the house quiet again.
But honestly, I feel lonely. And I cried when they pulled out of the driveway.
When I shut the front door and turned around the house felt empty.
Three hours ago I was yelling at a 4 year old for dumping out the entire container of glitter onto the table. Now my ears are ringing due to the silence.
I was sick with an ear infection and a sinus infection the entire time they were here.  You'd think I'd be wanting to take a long nap.
But it's not true. I don't feel like napping.
I have a stack of books from the library but I don't feel like reading.
I'd like to work in my garden but it's raining...again.
To tell ya the truth I feel a bit lost. And not quite sure what to do with myself.

What a ridiculous complainer I am.
I'm lonely.
It's raining.
These books are boring.
YOU DON'T DUMP OUT THE ENTIRE BOTTLE OF GLITTER!

I've just been handed a gift of a few hours to myself.
Time off from the grand kids and housework.
Six hours of nothing but free time, six hours of me time.
And I don't have any idea what to do with or for myself.

What would you all do with six hours of uninterrupted free time?
I'm taking suggestions.

Thanks for reading,
Love, Lolly
