I arranged a meeting/interview with a radio presenter recently as part of my PhD research, which took place in person. I wasn't starstruck, it's not someone who sees himself as a celebrity. But when I arrived the first thing I said was "God you look good in those glasses." It was just an instinctive response. No it wasn't Chris Evans, it's someone I've never seen wearing glasses before.
I feel a bit silly! God knows what he secretly thought!
