Playing games at home

In the weekend me and my cousin played games and it was called GTA5 and we played online. Me and my cousin played online and we vs other people. Then we played black ops 2 we played multiplayer and beat him and I said, “You suck and he said, “Come again”. So we played and I won again and he said let play another game and I said why you suck at it. Then we played MW3 and it was cool he said I can beat you at it and I said come on then. After that I beat him and he said you're cheating and I said no just because you suck at it.
