Talking can be embaressing but as soon as the conversation is over I completely forget about it. It is daunting speaking to people I don't know but I'm just used to it I guess. Think of it this way... Nobody cares. If you met somebody today with issues walking, would you continue to think about them after they're out of view? No because you don't care. People won't remember your embaressing moments like you don't remember there's. Don't sweat what people think.
