P.S. 1 - Snorkelling is really fun. I even managed to dive under and blow the water out of the snorkel when I came back up, though I think that I probably looked totally graceless and also I don't think you're supposed to have to come all the out of the water to do it. Still, it's a start.
P.S. 2 - the bruises on my legs are REALLY ugly. Note to self: learn to dive.
