You are a great friend. Does your friend need a ride to the store? Maybe just driving him somewhere like that would help him feel like he was out doing something--if the bright lights and commotion are not too much.

Maybe there is a quiet local coffeehouse? Movies and bars are not a good idea right now. I am really sensitive to noise, but last night I was able to go to a AAA baseball game at an outdoor stadium. I guess the noise had a place to escape. Walking is good. Puzzles are good--maybe cribbage.

I am sure it helps knowing that you are still his friend and you still want to do things with him. Have you asked him for ideas?
