If I used combat, idpa, real life, tactical, or scenarios in a sentence I'd certainly die a little inside.
heres what I do -
"so what do you do for fun?"
"I shoot a lot"
"oh that's cool, what do you shoot at?"
"I shoot USPSA, I basically run around and shoot things. It's a lot of fun.."
"..oh.."
"yea, here's a video"
"oh wow that looks awesome!"
then they ask a bunch of dumb questions and I answer them in laymen terms and be real nice and invite them to go and offer gear and training prior to match day. They say things like "yea that would be awesome" and then say things like "I've been thinking about getting a gun.." and then they never show up or care to shoot. Gets old
