September 6th       Dear grandpa and grand ma, Stockholm is fantastic! The weather has been perfect. It is sunny! The hotel and the food are ok. We had “fika” in a cafe in the Old Town. The Royal Palace is too beautiful for words! Swedish art and design is amazing! Phuc loves it! Mum and Dad have rented bikes. Tomorrow we‟re cycling around to discover the city, Wish you were here! Love, Hanh Mai
