My wife is a type one diabetic on an insulin pump that continually monitors her blood glucose, but isn’t always accurate.
Cheryl: I might need a glucagon shot.
Me: How much did you over bolus, actually wait, have you actually checked your sugar, or are going going by what your pump says?
Cheryl: Uh…
Me: Check your sugar with the meter.
I wait patiently for her to check.
Cheryl: Never mind.
