Over the years I have fallen because a stone was unstable and turned under my foot. I've fallen because I put my foot down wrong on an uneven surface and turned my ankle. I've fallen because a surface was slippy, but today was the first time I've fallen because a surface was too grippy! Apparently the surface down at Cardiff Bay is notorious for causing falls. Normally if I trip, I manage to turn it into an inelegant stumble and carry on, but it felt as though something had grabbed hold of my foot! Gravity took over and I now have a slightly grazed and painful knee and a sprained wrist. Also I broke my phone screen. :( Hoping to get that fixed tomorrow.
