I invariably come away feeling like people can always tell I'm a freak (no specific reasons for it, I make polite and interested small talk and express gentle enthusiasm for other people's stuff, my energy is just off, I think).
I am in my mid 40s and will always be bothered by this a bit but thank God I'm over the hump of being young and feeling the need to find my way.
I wonder what it's like to just go to events and not feel fear about it beforehand. It must be nice.
