I'm sorry if this looks a little nitpick-y, I'm just trying to help :) Also, nice colors in the photo.
On a side note, were you by any chance in the underpass near Sofia University aroun 1:30 PM today? I walked pass someone and I heard they were talking in English and used the word "Bulgarian". I turned around and saw one of the two people was a blonde girl. But by that time they were too far for me to ask "Carolyn?" without sounding weird.
