I prefer using higher precision when responding like this. I will often say something like: “137.825%”. Mostly, I do this because it makes the other person feel awkward, and I do it because I constantly feel awkward, and so I just want other people to feel a tiny portion of what it’s like being me.
The thing that most disturbs me is how cavalier the bystanders were about the guy having a gun, which the group proceeded to fight over. They’re just sitting there filming and providing commentary. My ass would be out of the pool, out to the parking lot, into my car, and driving home.
