Daughter wants to force us to attend Senior Center. How can we get her to leave us alone?

Anita, ask your daughter why she wants you to go. I assume it's because she thinks you could both use to get out more. Just because there is an activity posted doesn't mean that's the only thing that's going on, there always chatting and lunch and other informal activities.

As to transportation, discuss the options for that with your daughter. Just give it a try a couple of times to appease her, is what I'm thinking.
