We live on a busy street. During traffic hour in the evenings, there is plenty of noise outside and it just so happens to be windows-open season around here.
Madrileños use their horns with reckless abandon, and it's completely normal to double park and then when the blocked-in people need to move, they just sit in their car and hold the horn down until someone runs out to move the double-parked vehicle.
There are sirens, motorcycles revving their engines, dogs barking, and general city life.
There. Now I have set the scene.
A little bit ago I was sitting here on my couch, because it's what I do, and after a few minutes I registered an annoying beeping noise, and then immediately disregarded it. It's traffic hour.
Must be a delivery truck backing up.
10 minutes later I'm thinking that someone really stinks at backing up, but who am I to judge since I have to give myself a pep talk to even drive forward in the city.
5 minutes later I realize that all of my neighbors probably hate me, because it was time to flip the pork tenderloin. Oven alarm.
I didn't recognize the sound since it so rarely used.
