General tips. Don't use a mic. They will never know. If you need to use one. Speak as little as possible. If you go by this you let your skill do the talking. I come across just as many adults talking fraff constantly to be just as annoying as an overexcited kid. Only fools feel the need to step on others based on their age or some other excuse. In which case you are better off finding a solid group of people to play with rather then superficial or shallow people.
