Why bathe? You’ll just get dirty again.
Why brush teeth? You’ll just build up plaque again.
Why go to the dentist? The filling will fail.

Here’s smart choice #2 that will be annoying but tolerable for two more weeks that won’t kill children and teachers and their families.
The zeal is on the re-openers.
