There are some conversations where it is just so interesting, but you don't have any knowledge about or have any chance of participating, that was me today. When a topic gets too specific into a certain area that is unknown to me I'm just speechless, can't even think of relevant questions to ask even if I am curious about it, as much as I try to understand what others are saying I can't help but just be there, staring. At the same time, I think it is better to say nothing than being full of shit... so I'm just mute.
