You need to translate it to real life. I'm 34. I wouldn't play cards with a 13 year old. I wouldn't play soccer with a 13 year old. I wouldn't go get coffee and chat with a 13 year old. Do you see the trend? It's not a personal thing, it's just not done. Age groups tend to congregate together throughout life, it's a normal human thing. Why you're treated disrespectfully is a different story. There is no excuse. But, generally the type of person who is into games like this is not strong in social graces. I say this with sincerity and without rancor. You would do better not playing this game for that reason. We treat each other poorly here, and on other games like this. Always have, and always will. This isn't where you want to be learning what's ok and not ok to say to people, otherwise you'll be stuck like most of these guys, playing this game for 100 of hours when you could actually be doing something constructive and social. Like dating, or a legitimate hobby. Stick to local multi-player, where you have to at least share space with your friends.
