...We watched the cevemony of the Changing of the Guard outside Buckingham Palace last weekend. lt took place at 11:30 and Antonio missed it because he arrived late!Then we went to the Tate Modern;it was an old power station but now it's an art gallery.lt's really cool! The things there are weird but fascinating-l studied some of them in art at school last term.We finished Sunday afternoon with some shopping in Oxford Street(zzzz!!)and Robyn bought some souvenirs.
