HAHAHAHAH you are so fucking uninteresting. Everyone, FUCKING EVERYONE does that. It's not a talent on your part, it's a talent on the part of advertising to pick the optimal time length. The light thing is just learned. Fucking everyone knows when it will change.
HERE IS MY TALENT
I KNOW ON TV SHOWS WHEN COMMERCIALS ARE OVER
I KNOW HOW LONG IT TAKES FO RELEVATOR TO REACH MY FLOOR
I KNOW HOW HARD TO PUSH TO CLOSE MY DOOR WITHOUT LOOKING
I CAN FILL CUPS OF WATER WITHOUT LOOKING TOO
btw you start way too many topics for how little you have to contribute.
