When you forget your mask and you need to go into the store.
Ha! I forgot my mask the other day and needed to buy something at the convenience store. There was a new sign at the entrance that said "no entry beyond this point without a mask". What to do?
I found a big napkin in the car at stuck opposite ends of the napkin in my ears. Works great!
Necessity is the mother of invention, LOL.
A lot of people are letting this lockdown get under their skin, me included sometimes. However, it doesn't help matters to get twisted all out of shape over things you can't personally do anything about. There is a lot of debate about the efficacy of wearing masks. We will probably not know how much they help until later. I just hope people with decision-making power make rules and choices based on common sense and facts rather than emotions going forward.
