Background
I am blind. I work as a software developer in a company. I hate all kinds of gatherings. If I have a choice, I would spend my time alone with a computer.
Situation
I was attending my company's christmass party. There are series of plays, shows and music that would be performed by each department. When the first performance started, I began to take my phone out to read a book (I am not interested at the performance). Suddenly, a manager sat down beside me. We did some small talk for awhile until he started describing (in detail) things that are happening in the stage for my benefit. For example, when people are laughing, he would stop just to explain why something is funny. I was shocked at this manager's kindness. I absolutely did not expect someone would do such a thing. Although I was bored out of my mind, I acted like I am interested (to show my appreciation). After all, not anyone would take the time to do what he did (even for people like me).
My question is: Is there something I can say to escape this situation without hurting the manager's feelings? I mean, I really am not interested in the performance, not his commentary.
