Suzy,
I hope this doesn't mess with your mind as it were but did you consider that they suspected you? That it was an attempt to provoke a reaction? Not in the sense of outright rebuttal or defense of CD's but to look for those subtle "Tells" as the poker players say, the slight blush of embarrassment, a shift in posture, oh so many ways in which we subliminally react to these situations that says,"Gotch ya".
Or this could be just another of my daft conspiracy theories.
But in defense of leaving the closet. It's a bit like reading the statistics for road deaths in say somewhere like India as using that as an excuse for not going there on holiday or for that matter even leaving the house in the UK. It's all too easy to focus on the negative and end up missing out on wonderful experiences. Having said that I do truly respect your decision. It's as valid as any other, certainly mine.
