Naresh and I went to Amsterdam. We met up with Floor and Lori, who told us, in no uncertain terms, that the one not-to-be-missed-attraction/event in Amsterdam is Nemo, the children's science museum.
They were so serious that they even walked us there after it closed so that we wouldn't get lost when we went for real the next day.
They were so serious that we went.
We got inside bubbles and talked to a giant robot (but not at the same time).
