I learned just how little I actually need to go to a store for things. I tend to let them build up and do them all in one sweep rather than here and there like I used to.Also, 's grocery pick up is awesome! I save so much time and now only get what I need.
I learned that having good neighbors is a blessing. Back in March, my wife and I had to quarantine because I was exposed to someone who tested positive (ironically, it was in a training course about remote learning!) I texted several of our neighbors to let them know since at that point we didn't know how easily the virus spread. They were terrific, offering to pick things up from the store, asking if we needed them to walk our dog, etc.
It's easy to put a mask on without any hair around your ears!
I learned something about humanity. If people took this virus seriously and kept their distance, this virus might have just fizzled out long ago. Here in RI, people are getting their first shot but not getting their second one. I checked the numbers for infection this morning and they are still climbing. I think people are becoming complacent and pretty much doing whatever they want. Two things are infinite, the universe and human stupidity.
