I don't know if you have them in the US, but in the UK we have got these places where you shoot each other with laser guns. You have to wear a kinda belt. And you only score a hit when you shoot the belt, from what I remember.
I think the name is Quasar, or something like it.
And there were several of us brothers who went to one of these places years ago, when I was 17.
Each of us had to have a chat in the back room because of it.
Shooting each other with laser guns apparently wasn't Christian, lol.
