Kirk

“To say that Richard Mayhew was not very good at heights would be perfectly accurate, but would fail to give the full picture; it would be like describing the planet Jupiter as bigger than a duck. Richard hated clifftops, and high buildings; somewhere not far inside of him was the fear – the start, utter, silently screaming terror – that if he got too close to the edge, then something would take over, and he would find himself walking to the edge of a clifftop and then he would just step off into space. It was as if he could not entirely trust himsels, and that scared Richard more than the simple fear of falling ever could. So he called it vertigo, and hated it and himself, and kept away from high places.”
― Neil Gaiman, Neverwhere
