Today part 3

This morning at work,
People go to me to have a little laugh,
I am kind of sharing my sleepless night story,
My hair unbrushed either,
I washed it, but didn't brushed after,
Some joke comes on mind,
Person use head to stop on the slide.
People asked me,
What do I wear at night?
I said, I wear clothes,
But not socks, sweater and jeans...
