Day one of isolation has been a rip roaring success. Thanks for all the suggestions, everyone!!!
A quick rundown of what we did:
Dance party (with Sam's guitar shirt providing our music)
Paper airplane building
Watched pink panther shows
Played a few games
Sat on the floor on a blanket (change of scenery)
Threw the paper airplanes at the staff
I sincerely hope we didn't use up all our activities in one day.
So far this seems indefinite. Lucky us.
