There is a movie offered at our local college. I would love to go with my husband who has Alzheimer's. Why am I so uncomfortable?

I'm guessing you are somewhat fearful your husband will act out at the movie and disturb the experience for other attendees. Being raised in an era where consideration for others was a primary consideration in our actions occasionally has a down side. I suggest going to the movie and taking seats near the end of a row and maybe forward where fewer people sit so if you feel the need to leave it will be easier. Enjoy what treats you can while you can.
