It's fine to know it happened in the back of your mind, but to imagine it taking place. Especially among folks I'm supposed to be thinking of in a platonic, non-sexual sense (like, as in, NOT normally considered sexual beings)...
But, whatever, it doesn't bother me. It's just, if I had the choice, I wouldn't really care to have the thought cross my mind.
“…Judge not what a man has done, but judge what he could have done if he was a different bloke altogether. For art thou a leper? And a leper can changeth his spots…” --Rudy Wade, Misfits (Series 4, Episode 8)
