My boyfriend's mom--as much as I love her--has 2.5 topics of conversation, to my knowledge:
-Zumba/her friends from Zumba
-sometimes cycling
-DBF

I know she teaches Zumba (as part of her second job), and DBF and his dad tend to monopolize conversations about cycling, but still.

Beekeeping is at least interesting and isn't something most of us know much about.
