Somewhere in a bathroom drawer, you have a peel-off mask or other form of facial stuff. Or make your own; some recipes are at https://www.thehealthy.com/beauty/face-body-care/homemade-facial-masks-recipes/. If you live with someone, get him or her to do it too. (Men like facials, too!) Take pictures of yourselves masked with foamy stuff and send them to someone who needs a laugh.
Try some brand-new operas
Philadelphia Opera is offering a short opera series in May--four world premieres of very contemporary works and one classic, The Barber of Seville. Check out the list at

Memorize something
Stretch those brain cells! A musician friend is memorizing some Bach, a few measures a day. Or a poem that makes you laugh, some helpful quotations, the state capitals? If you're feeling blah at this point in our quarantine, this may give you something to feel good about.
