Last Saturday, I went to the Phillips Collection with my friends John and Jill. We wanted see an exhibit of Japanese prints. The Phillips is my favorite museum. I have gone to this museum several times last year and I have seen many wonderful exhibits. The exhibit on Saturday was very interesting exhibit, too. We all liked it very much. After that we visited the exhibit, we had a delicious lunch in museum’s cafeteria. We think that we will go back to the museum next Saturday to see the exhibit again.
