A few days ago, Mom got in touch with my FMIL to chat about shower/stagette-related things (Mom and my sister are planning this). Both of their phone numbers and email addresses are on the invite. My sister's address includes her middle initial, which is "C", and FMIL asked Mom if it stood for "cabbage", and if that was her nickname. Then she laughed. FMIL likes to "test" people (I don't know what this means), but Mom felt a little upset by this, as she didn't name her children after vegetables. Not sure if this should just be blown off, or if someone should say something to her next time it happens, if there is a next time.
