"Don't get too close to my knife," she said, nonchalantly.
I lifted the pillow next to hers and saw a 10-inch butcher knife, lying at the ready.
She explained that her alarm system and phone service were on the blink and that they were somehow tied together, electronically. The knife was Plan B.
I was tempted to point out that she is a 76 year-old woman, 5'1" and 100 pounds, who, in the middle of the night, might be easily overpowered by an intruder who could use the knife against her. Then I thought, why deny the woman precious peace of mind?
As I've gotten older, I've learned it's often a better idea to just hold your tongue.
