You were visiting Gravity Falls and heading to some dumb tourist trap, the 'Mystery Shack'. The guy who run it, Stan Pines, was a huge conman. Though his great niece and nephews were way dorkier. especially Milo, a kid who seemed around your age, sitting on the stairs, typing away at whatever it was on his laptop. You looked over his shoulder and it looked to be C++ code. (best coding for 3D games I found out through googling for this) He was 'on the job', but wasn't paying attention to it at all. You didn't really know anyone else there, so you got his attention by tapping on his shoulder. He jumps a bit at you tapping it. But it manages to get his attention. He looks up at you and quietly says

"Oh. Uh.. hi. I should probably greet you since that was what I was assigned to do by my great uncle. So, welcome to the Mystery Shack I guess... I'm Milo."

he says with his nose still in his laptop, but his eyes still looking at you
