This rang so true to me and made me laugh. Derren is talking about his admiration for Helena Bonham Carter and in particular their attendance at a VIP gathering after a Rufus Wainwright show. "Since then I have found myself alongside her many times, normally when in Rufus’ company, but never said hello. On each occasion I pass by imagining she wouldn’t know me from Adam: then, when I leave, I wonder if she might have done, and whether I had seemed rude. Such are the conflicts of C-rate celebrity."
