Pickles, faffing and issues with toast

Today we made it as far as Kings Cross in London. We've walked some streets three times and haven't been able to make it to places we hoped - but it has been fun.We got stuck on Oxford street with the annual pride march - crazyness. I tried to explain to L why some men were walking the street in high heels, bunny ears, tutus and pink wigs. She was very interested in going to Tottenham Court Rd (one story in Harry Potter) so we did without me asking first what the story was about (I found out later it was about Hermione having a sludgy grey coffee with Harry and Ron in a cafe and getting propositioned by a drunk man). We managed to have a lovely (though expensive) lunch and a great coffee, and also avoided the colourful street people. There are many parts that are pretty grotty though. L is exhausted this afternoon so we are going to check in now.
This morning we said goodbye to the M's. We loved spending the time with them - especially the younger two who have very developed personalities -J (4 years) is a pickle (cheeky ratbag) who faffs around (loves an audience - and is very cute), J (6 years) also has a lovely sense of humour. B (8) is an empathetic soul who has a gift for lego robotics, A (mum) has issues with the toaster (which was australian) and M (dad) is (along with A) is inspirational in the way he believes they are to enrich the community in which they live. M also volunteers and trains red cross first aid people in the area in his spare time. I had no idea he loved that so much.
We hope to walk along the Thames tomorrow - we saw the miniature version of most of the sights yesterday at Legoland (detailed - and infinitely more manageable) and also flew over it on the way to Heathrow on Wednesday. Today i've managed to stay out of too much sun after getting sunburnt at legoland (and bottles of sunscreen are £15 in london!). Tomorrow afternoon we fly to Holland - I am sooo looking forward to seeing the R family there.
Tonight we are off to stay in the Clink Hostel in KC - the old magistrates court complete with cells for bedrooms (L's request). The place we left our bags this morning resembled the room of requirement (Harry Potter) where things can be hidden forever. I hope they will be found when we get there in 15 mins. I think Clink may complete my picture of London as a little claustrophobic.
