He just texted me:
"Hey, Jess. Mom just told me Ruby-Lee might have a hearing problem? Her Papa thinks she is perfect anyway, it's okay! "
He was really disconnected growing up, but his grandkids definitely have him wrapped around their fingers.
(and "Ruby-Lee" is his nickname for her. Lee is his middle name and I think the double name thing is a throw back to all his time in the South.)
