Questions for you: What my father has done, is get involved in a convo with a man at the table, and put his back to the dancing. If asked to join in, he has to “check his cell phone to see if he just got a call.”
Also, he doesn’t stay the whole time, tries to come for the important parts, and lengthy dancing usually is something that you can be yotzei by sitting on the side, with ur back to the dancing, or dancing with men.
