A monastery custom that visitors often first notice with a certain degree of perplexity, but get used to real fast, is that whenever a bell or a chime sounds, sometimes even a phone ringing, but not windchimes, everyone immediately stops what they're doing and goes still and silent. This part of the practice of mindfulness is to always be prepared to clear and calm one's mind.

I considered if there might be a similar substitute at home for this, and I jokingly thought that instead of the sound of a bell, I can use the sound of fire trucks going by. I've been home just hours, and I'm thinking seriously that fire trucks might work!
