I know all of you have been waiting patiently for this week’s tutorial. But I’m sorry to report there isn’t one. My dad (83) was admitted to the hospital (in another city) early Friday in serious condition. He’s okay, and has been discharged, but I’m mentally and emotionally exhausted. I hope to be running on all cylinders again soon. Meanwhile, stay home – flatten the curve! Take care of yourselves and the ones you love.
