You don't have to wear one always and everywhere! But every time you do, you and the people around you are a little bit safer, so find some places it makes sense for you and start there! I've got a train trip tomorrow and I'll have mine on.
Ward Q. Normal (he/him)If you haven't been masking, give it a try. What do you have to lose? Just wear one in crowds and on planes, trains, and buses. Find a style that fits, so you don't futz with it. You don't have to get sick all the time.
