A few of the people in the pictures are clearly pulling 'wtf are you doing posing for a solo photograph in a really busy public space ffs' faces. A few of the others though ... Not so nice. Feel slightly guilty on seeing the pics because I'm not even gonna pretend I've never made those sort of faces.
