Writing a postcard

Mum and Dad,
I in London for 3 days. I am really happy, I lots of beautiful monuments. I Big Ben and Buckingham Palace, I in an Indian restaurant, I a few tee-shirts and I 2 museums. I really lucky so far because the weather really nice.
Yesterday, I a fantastic day. First, I to Westminster, and a boat. I at Tower Bridge and on it. Then, I took another boat and continued to Greenwich. There, I in a typical restaurant and I even a beer. Then, I up to the observatory where I for 2 hours. There is a lovely cafe there, I 2 German students and we a drink together.
Tomorrow, I visit a museum. I to the Science Museum first and then to the Natural History Museum. On Sunday, I to Camden Town. I to doing some shopping there.
I miss you, but I lots of fun.
See you on Monday.
