You've heard a bit about the trip on L's blog, but here are some pictures...
There was also a bit where kids could put on a climbing harness and climb rigging...which Sherlock loved, as you might imagine. Although he did argue about the climbing harness for about five minutes before he agreed to put it on, on the grounds that he wouldn't have had to if he'd gone to sea a few centuries ago and he'd have been in battles and everything and he bet there were pirates somewhere in the world right now that would let him climb things without a harness, which he didn't need, at all.
I told him that poem-- All I need is a tall ship and a star to steer her by -- and he decided John Masefield was obviously a pirate. Nothing I said could convince him otherwise. Are you sensing a theme?
L and Mycroft and I have heard the word pirate so many times since that day that I think it's lost all meaning for us. Piratepiratepirate. He was so quiet in his room after school yesterday that I went up to check and was shocked to find him doing his homework and not, as I had suspected, making pirate hats for the degus.
