yep

Usually when I play blindfold, it's because I'm playing several games at once and one of the players is across the room. We call the moves across the room, and my opponent moves both sides, while I continue the game(s) at my table. There are exceptions. When my son thought too long after we had each announced one move to start a game while waiting for the plane, I got a magnetic set out of my bag. The rest of the game, he kept the set concealed from me and made me play "blindfolded". We were in the air when I missed a mate in one in the late stages.
