house of bricks

Hello again, anxiety.
I wish you'd thought to RSVP.
I really don't have time for this-
You use up all my resources.

You dropped in uninvited,
Did you think I'd be excited?
I know your games, I know your tricks-
A house of straw, a house of sticks.

You're a wolf and I'm three little pigs,
And though there's no hair on my chin,
I've built myself a house of bricks-
You've consumed me twice, but not again.
