Be careful what you offer to do for a friend just to be nice. There may come a day when you have to make good on that promise, and you might just run out of friends to offer up and throw under the bus in your place. The real test will be when it comes down to the last minute and it looks you may just have to go to the theater to see the live dancing show. At that point do you suck it up and go, or do you get a last minute case of the runs so bad that you can't even leave the house?
