“I’m absolutely terrified of being tied up.” “The thought of a blindfold can make me physically sick.” There: two things that only a very limited number of people know about me, and even less of them understand, or try to understand. Very few have watched the change in my demeanour and behaviour if I come into contact with items specifically designed to restrain, or the way I burn up and my eyes fill with tears at even the mention of a blindfold coming anywhere near me or, by extension, the very mention that it might.
