My beloved Grandmother was a corporate firebrand, who made male executives quake in their tasseled Florsheim loafers, long before the so-called "Women's Movement."
She's not much into talking on the phone, but then she had her own secretary so she didn't have to.
So anyway, she called to invite the whole Infidel clan over to her home for lasagna since we'd gone without electricity for so long we were turning into an indigenous tribe of Caneaters.
After the arrangements were made my Grandma was anxious to get off the phone. In her haste the best line she could come up with was a flustered "I have to go right now because the battery is running low in my...............(long dramatical pause)..........in my FIRE ALARM!"
Preparing for the future doesn't just entail food and water and all that stuff. No, a prudent person should also have a handy dandy list of viable excuses ready for immediate use at all times.
*Thanks Grandma. The lasagna was delicious!*
