I’m at a lot of demos and protests. Sometimes it’s noisy; speakers from the stage, bullhorns, conch shells, etc. So, when I try to call Sue or she tries to call me, often we can’t hear the phone ring or hear the other if we do answer.
My solution:
Create two Quick Note messages on my cell phone. These are short messages that you type in advance, then send with a couple of clicks.
So, if I text Sue a Quick Note saying “Loud demo,” she’s knows not to even try to call. After the demo has concluded and the noise subsides, I send another Quick Note saying “Loud demo over.”
