Is it normal i close my mouth and think hard.

I was walking accross the other street and there was a split in the median

(median is a section of road that splits the road so busy streets can drive and make turns)

anyways there was a split in the median and cars were coming from both directions. I closed my mouth and thought deeply about timing and distance as well as speed.

I did it perfectly, no cars honked, nobody yelled, no one was injured.

it was pretty skill full. but that's besides the point.

I never get honked at and lots of people are fascinated with the way I do that. people meaning all the people who are crossing the road and they fall behind or sometimes even friends

but what I want to know is... is this normal? and if so why do I do this?
