You can't wash just one hand

Yes you can

Being real, this is the kind of shower thought I prefer.

This particular one is inaccurate, but it's still a proper shower thought; something that you might think of idly while your body is busy and your brain is on autopilot.

But what if you only have 1 hand?

Lmao watch me. Someone's never had a cast before

Ableist! some people only have one hand. Some have no hands. Be mindful

If your showerthought is true, then what do you suppose that I have been doing while shuffling aimlessly through life since the invention of paperback books and smartphones, eh? Living like a pig? How dare you.
