Martial Arts Discussion!!!!!!

I practiced Kendo for a year when I was in the seventh grade.
My grandfather had some kind of high rank(?) in Kendo, and he was obsessed with the idea of training me as a good Kendo fighter.
I really didn't like the idea; wearing those smelly armors was disgusting, and I just didn't like fighting. But I did it anyway to convince my grandfather, and I quit it after a year of simple practices; swinging the sword up and down and tripping into the world of zen or something like that.

After all of those training, I learned that I really suck with Kendo, and my granpa seemed to understand that clearly, which rapidly burned out his motivation of training me.
I really don't see the point for training martial arts, and I learned that screaming out loud or throwing nearby objects works just fine to get myself out from some dangers.

This question is going to look dumb in a martial arts thread, but for the people who practice martial arts, why do you practice martial arts?
I'm just curious, nothing else.

Jam it back in, in the dark.

I know that you will lose your title if you use your skills on the street (if somebody tells the "Sensei" that you used it), but have you ever used your martial art skills in a daily fightings or something like that?
I'm not talking about those official matches, I'm talking about the fight that you might have between your friends or somebody from the streets.

I've seen some fights, but all they did was smack and grab each other like little kids do. I know that those people did not had an experience with martial arts, so I just wondered whether you all do something nice/clean/cool when you have a fight.
Again, just curious.
