As someone who has worked from home for years, I have the self-entertainment down. I'll be working on some of my stock-piled stitching projects, but realize that not everyone has a craft or hobby they engage in.
Our plans have changed for D's vacation next week, and we are staying put. The raised beds need to be cleaned out and our back patio needs some attention. And, of course, the dogs will need their regular walk about next week.
If you're stuck in the house and want things to do beyond binge-watching TV, check these sites out.
Needlework & Crafts:
Looking to learn a new language? Sites like DuoLingo and Babbel provide free exercises and lessons. I need to get back to my Spanish lessons so next time I'm in Oaxaca I can buy a new suitcase to haul back all the mezcal (true story---I managed to navigate a department store purchase last year for this very purpose. Thanks DuoLingo!).
This might also be a great time to take a course on Coursera. If you're not into a certificate, their courses are free.
Don't forget: a lot of fun can be had with a deck of cards. Bicycle Card Company's site lists rules of play for all kinds of games--even solitaire.
