The Alarm Clock
You always know what time it is, and you feel every minute of it.
You know exactly how long until the next thing, and the thing after that, and you feel those minutes. You are reliably on time because being late sits hard with you. The tradeoff is that the clock stays close. You’re not tense about everything, just about the one thing that never stops moving.
"I'm an Alarm Clock. I'm almost never late, and I feel time closely."
