Got to work today and was asked to attend a conference. Today. (Thanks for the warning, guys, go team.)
I went, and caught up with a heap of work contacts who didn't know I was coming (ahem, nor did I). Anyway, lots of (genuine) "it's great to see you!" which always surprises me.
Also, a guy tapped me on the shoulder and called me by another girl's name. When I turned around he was mortified, and apologised. Wrong person. Later I was introduced to the girl he mistook me for. She's cute! :D
