Nerves

My boyfriend and I are doing a triple date here saturday, and I'm having nerves about it.  There's nothing to be scared of, but I'm racking my closet for the perfect outfit, hoping the food isn't too fancy, that conversations go smoothly....Does anyone else get like this?  It's my anti-social/scaredy-cat impulses fighting my fight or flight responses.  I've never been to this restaruant, but it's in this great neighborhood full of a couple of my favorite places, (like this, this, and this) and we walked by once while there was a wine tasting happening.  It seems so very adult and grown-uppy!  (which is clearly so not my thing.....ha!)
