Yeah, that was me in Paris last week. In case you are curious, mask compliance in France is very high so hats off to them. No bandanas, gaiters, scarves, not even cloth ones, good old paper masks. Depending on where you live and your lifestyle, the need for almost constant masking may be news to you, or it may be business as usual. I thought I would just roll with it, but I did some math after my return and it's really something you need to consider as part of the "new normal."
You will put on a mask for the taxi to the airport, you will wear the mask the whole time you are in the airport and on the plane, if you're connecting you'll be wearing it in another airport, and then when you land you'll wear it in THAT airport through immigration and baggage claim and then in a taxi to the hotel where ... you will wear it until you're in your room. That's a really long stretch of mask wearing.
Once on the ground, you will be wearing the mask basically anytime you are out of your hotel room. Even outside many Parisians are wearing their masks, partly I think because it helps keep your face warm and partly because it's such a PITA to take it off since you're going to just put it back on. You'll be wearing it in churches, museums, restaurants, stores, taxis, metros, buses, trains. All. The. Time.
We found the airport/plane masking to be the most uncomfortable and nearly unbearable since it goes on FOREVER, in fact when I got home I had sores on my ears and had to use some Boudreaux's Butt Paste to help them heal (gotta love that name).
