Pride is a hard thing to deal with. It's a very dangerous beast, especially when threatened or damaged. He laughed at you? Bit rude, but if you saw someone else do it, would it be funny?
Usually, when we're a beginner at something, we fail, and fail, and fail some more. It's whether we continue to try, failure after failure, that determines if we'll improve.
I laugh at my failures sometimes, usually things that require coordination above and beyond me, and it gives me the energy to try it again anyway. "Oh I forked that up bad! I must have looked like an idiot! Just like always! Haha. I'mma go do it again. Hey (insert name if I can remember it [I really fail at remembering names]), could you show me how to do that? I still can't get it. I'm sorry that I forgot again, but what's your name?"
