Just Trust Me Bro

A time in my life where I had to convince someone that they could trust me was actually a few days ago that this happen. When I play video games I play on the Ps3, so I met these guys one day while I was playing. So they asked me if I wanted to join their game so that we could team up and play together, because I am like the best Call of Duty player ever. So after a while we all became really good and close friends for almost two years now. This game called Mine Craft came out for the Ps3 just recently and I wanted to get it. My friend wanted me to get it also so that we could play it together. I told him I had the money but no ride to get the game. So my friend that lives in Texas said that he would just go run to the store and buy me a money card. Which he would then send the code to me through the Ps3. I had to convince him that he could trust me and that I would pay him back the same way. I told him if I make promises to people, that I keep my word.
