My partner is always going on at me, saying I'm obsessed with rock climbing. There was a time when I was frightened to answer her back, but I'm much boulder now..
Reminiscent of the old joke about when I was edging my way along a mountain ledge and met a young woman; there was only room for one of us to pass the other. I didn't know whether to toss myself off or block her passage. (copywrite Max Miller).
