Do you ever done something?

Many people always like to say "Do you ever done something?". I think he's mean "If you don't have this kind of experience. You are never and never to convince me.". I admint I am a man of bad words. In this situation, I always stop to talk to them, but that not mean I was convinced. Because I think he was losting the thinking ability of objective. Reversely, they sometimes may try to convince you. And you always don't know what they talk about. There are too much contradiction in their reasons.
