So glad to hear other people are afraid of the same things as me,particularly heights. We spent a few days in Bristol last year and I took it in my head to walk over the Clifton Bridge, and accomplished it, not looking over till I got to the end, then walked back again trying not to think about it! But I'm useless with even my wee set of household steps, the first one gives me wobbly legs! And my main fear is getting locked in a public loo,I refuse to use the unisex/invalid ones,rather wet myself!
