Elevators Lifts have this cool accessibility feature where, depending
on whether they’re going up or down, they’ll ding once or twice when they
arrive. This is so you know the direction without having to look at the display
above the doors.
I’ve finally come up with a mnemonic for remembering which is which:
- One ding for going up – think “to one-up someone”
- Two dings for going down – think “to double down on something”
