Yes...don't pay attention to your opponent's (s') hands.

Yes. Also, my cousin is in a group and they've won many contests.

No. I don't like getting wet that way. 

Yes.

Yes, lots of them.  Most of them involved dinners at nice restaurants. One was in my neighborhood, a classy Northern Italian restaurant. Nice salad with pomegranate seeds, Dover Sole with vegetable and potato, Napolean and coffee/tea. It would've cost over $30 if I had to pay. Of course, they make you listen to the presentation first; the meal comes after. If it was, vice-versa, a lot of people would bail out after the food. I have an otherwise expensive meal coming up soon  at Morton's soon.  https://www.google.com/search?q=mortons+steakhouse&ie=utf-8&oe=utf-8&client=firefox-b-1-ab

It's logical to me. Not to trivialize that adults have been killed during these incidents, but most of the victims have been kids. They are the "leaders of tomorrow". Up until these massacres started to happen, it was widely thought that if anywhere a kid was going to be safe, it was in school. Not anymore. Unfortunately, I'm sure that there will be more. There are plenty of "sick kids" out there, kids that have been bullied, feel unwanted, laughed at, demoralized, have family problems ( not that any of these justifies violence to a normal person), will finally get the attention they crave, albeit in a negative way ( "their 15 minutes of fame"; a lifetime, and "then some" of infamy is "more like it") and have easy access to guns.

Maybe pride? https://www.youtube.com/watch?v=1vZc_GZ-L_0
