Papa Lai and Mama Lai Competition

Mama Lai is traveling in Asia without Papa Lai.  Papa Lai has been sending me cute e-mails on how to take care of his wife, but even in the midst of the TLC there's always some room for some healthy, old people competition:

"[Mama Lai] is not good at falling, unlike me, so help her over stairs and curbs, especially when there's ice and snow."
