The power of Bubbe compels me...

I recently bought some new ice trays from Crate & Barrel. The cool
kind that are made from that space-age silicon and make perfectly
square ice cubes. Now I'm afraid to use them for fear that I won't
have any in case company comes over. I don't even have company over
all that much.

I've channelled my Grandmother (G-d rest her soul) and her plastic
covered sofas. Whom am I saving the ice for? Is Abba Eban coming over
for Shabbos Dinner?
