Big Boy's Suitcase

What I love about Big Boy is that he really knows how to make use of stuff, even if it's a different use than you expect.
Yesterday morning, Big Boy and I went shopping and got MrDartt a new lunchbox cooler for Father's Day. So yesterday afternoon, Big Boy annouced to his daddy that we'd gotten him a suitcase.
This morning, MrDartt opened his wrapped "suitcase" and Big Boy insisted on taking it up to grandma and grandpa's for our Father's Day breakfast. He carried it around the house and loaded it up with "work stuff" to take with us, including:
My tomato pin cushion (without any pins)
A tieback for the curtains in Little Boy's room
His shoes, in case his feet got cold (he wore flip flops to expedite his getting ready process because he was so excited to go up to grandma and grandpa's)
Two of his own socks
One of Little Boy's socks
One of my warm fuzzy pajama socks
Two dishrags
His Spiderman hat
A pink ball, which is part of a ball-blowing toy
When we arrived at grandma and grandpa's house, he took everything out, played with a few things and then put everything back in.
