Tuesday, 6:40 a.m., early call, kitchen light still on its weak setting. My current pen looked empty enough that I did not want to gamble, so I cracked the backup and wrote Tues 6:42 on the box with a Sharpie.
At lunch I held the old one under the stove light and saw there was one more use in it. Now I have two open pens, a Sharpie timestamp, and an inventory rule that just lost an argument with my morning eyesight. Not a crisis.
Just annoying: my whole system assumes I can see the plunger at 6:40. Next time I am putting the old pen under the lamp before I decide.
Do you run the old one down first or accept the two-pen week?
