My kids love discussing how family is related. I was telling them that Grandma Lang is my grandma, Grandma Goodrich is my mom and your grandma, and when you have a kid I will be a grandma.
Stella: "And Dad will be the grandpa."
Fred: "And he'll be the Big Scary Bear." (My Dad's favorite role.)
Stella: "Yeah, and you'll be the grandma and give lots of hugs and kisses."
A few days later, Dan was asking the kids what they wanted for lunch. Stella couldn't decide. Dan asked, "How about a knuckle sandwich?"
Chloe said, "Dad, that's only funny when Grandpa says it."
