Whats he doing with his hands by Martin Grice Lyrics

My socks don’t quite fit anymore
Something about my step has changed
New contact feeling foreign with the floor
And yet you’ve stayed the same

My new found belligerence
Is none of your business
These realisations mean nothing
Unless they are still interesting

I’m neglective of my shame
I’ve forgotten what not to say
What’s supposed to be embarrassing?
Am I a sociopath?

Oh oh oh oh oh oh oh oh oh
If I’m finding the detergent
I take barren
It's niceness
