1) Decide you’re too tired to stand up to shower, and elect to lie down and wash your hair under the faucet in the tub.
2) Forget that the drain is open when you lay back to rinse your hair.
3) Become immediately panicked when you realize your hair has partially gone down the drain and is stuck.
4) Flail frantically and scream until hair is ripped loose.
5) Decide that you will never again be so tired that you can’t make your lazy ass stand up to shower.
