Convo with granddaughter

Her: gramma your arm flaps are funny
Me, wiggling them:  yes, they are!
Her: did you know there are 3 kinds of bats (tells me what they are)
Me:  where did you learn that?
Her:  I don’t know.
Me:  Do you think gramma can fly with her arm flaps?
Her, laughing:  no, gramma
Me:  how about gliding like a flying squirrel?
Her, pausing…
Son/dad:  it’s not nice to make fun of other people
(he didn’t get the memo)
