So lately my friend has been acting like he's a pro paintballer, and it's getting on my nerves. He is always saying, "I'm too good for this marker," and "I'm an advanced player, so I'll easily be able to handle any marker out there." And he says it seriously. We are only 13 and just got into paintballing like a few months ago. He thinks he's like Justin Rabackoff already and it's really annoying. I keep explaining to him that we should listen to the people who work at the pro shops because they'll know what's best, because we're still beginners. He is trying to upgrade his Spyder Agressor to an Invert Mini, which I believe is a big mistake. He brags about how good he is and then once he gets to the field he cowers in the corner of the field while I have to take on more people from the other team. He's afraid to play with 10 year olds. Any ideas of what I can do to make him understand that we aren't pros and still need a lot of work to become good paintballers?
