And during a lot of this work, we found something, or I found something, that really fascinated me, and maybe you can remember it. Do you remember when lights used to just go on and off, click click, when you closed the door in a car?
Y durante gran parte de este trabajo, encontramos algo, o encontré algo, que realmente me fascinó y, tal vez, puedan recordarlo. ¿Se acuerdan cuando las luces simplemente se encendían y apagaban, clic-clic, cuando cerraban la puerta del auto?
