Will you put a mask back on in two months? Because 2 months is the earliest that someone has been documents to catch Covid again after an infection, and although you may have a mild case again, you still would pose a risk of spreading it to others. The main usefullness of masking is to protect other people, including vulnerable people and people who won't know until they get Covid that they are vulnerable.

The really misleading thing about Covid is yes, half the people who get it will get mild disease. (Most of the vaccinated will get mild disease). It's the other half we worry about, and you cannot tell in advance which half you will fall into.
