Fun and family
"We" got injections; that suggests at least all the kids, and maybe all of us. The only reason I can think of is our impending trip to Mexico. This was exactly one month before we entered Mexico, so inoculations against all sort of food-, air-, and especially water-borne diseases were appropriate. (Less than 15 years later, Tom Lehrer satirized the reversal of the problem in his song
"Pollution".)
I don't remember Frank and Frances. But according to the family tree, they are also Mom's uncle and aunt.
