really old

yesterday in the car, kate asked me why bubby mitzi and mema (jeff's grandmothers) lived alone:

me: because their husbands don't live with them any more.

kate: why?

me: well...they died.

kate: why did they die?

me (trying to make it as simple as possible): well, they were really old.

kate: so you die when you get old?

me: a lot of times, yes.

(a few seconds of silence as kate thinks about this)

kate: well how come mema is still alive? she's REALLY old.
