What is happening to my socks?

I search and search for them

But it appears to be a lost cause

I wash them and dry them and then

They disappear

Seemingly into thin air

And my feet are not warm

No, not at all

And so I search everywhere

Every room and down the halls

Trying to find my missing socks

I think I used to have a lot

But they've been coming up missing

their numbers dwindling

And I've put their pics on milk cartons

And on trees with the word 'Missing'

So if you find them, please call me

Tell me how they're doing

If they're happy with out me

Then send them back to me

For another year of foot-bound slavery
