Some measurements cannot be charmed. A scale reports the weight and has no interest in how the apples look or how convincing you are, and every so often you run into a person or a process that works the same way. The clock, the entry requirement, the stopwatch, the bank. Charm is a real skill and it has a boundary, and running into that boundary is a shock for anyone used to talking their way through.

Find the place in your week where only the number counts. Do the unglamorous preparation for that one thing instead of your usual workaround.
