I normally don't go out on weeknights, but a friend of mine called a short while ago to say he had an extra ticket to a concert. Ordinarily I would have gone with him, but I'm feeling weak and tired today and was concerned I wouldn't be up for the battle with my AV so I turned him down with a lame-ish excuse.
On one hand I'm glad that I recognized that I may have some trouble if I went, but on the other hand I'm annoyed that I'm in this situation. Regardless of the latter, better to err on the side of caution.
