Being middle class suburbanites that we were, my dad was the first in the street to install an electronic / remote operated up and over garage door. Having spent the morning rigging it up, he brought us kids out to have a go. French instructions spotted by little sister resulted in her being told that it was voice operated, and would only open to a loudly issued "ouvrir!!" Closure, of course, was triggered by an equally loud "fermer!!!"
There are two openers. One lives on the kitchen windowsill. The other lives near enough to dad to ensure the verbal commands are still observed. Thing is, she's 32 now, and she still yells at it.
Her kids have long rumbled it as a joke, but little sis continues to stand in the driveway shouting at the garage in French.
Mind you, she still thinks "Merde!" is French for "Sorry!!" and always makes a point of saying it on the Isle of Wight ferry.
