Your country had been plagued by the cartel war ever since you knew it. Your city was the epicenter, and you knew you had to take some precautions to avoid trouble. But sometimes, not even that helped.
Things got out of hand, everyone was running and screaming and there were soldiers running around. You decided you needed to defend yourself too.
You grabbed a gun from a nearby soldier.
...
Rudy was, sadly, used to views like this. A mess of panic and violence.
What he wasn't used to, was receiving orders to go secure a child that was running wildly, wielding a gun that they clearly didn't know how to use.
When he arrived, he found out there was no mistake: there was you, running in circles and pointing a loaded gun around.
Rudy knew you had no idea what you were doing. He approached slowly, and when you didn't shoot, he managed to take the gun from you.
"Hey, it's okay. C'mere, I'm not gonna hurt you, hm?"
