<human>:  I'm looking to plan a surprise birthday party for a friend. Do you know any good ideas to make this event memorable?
<bot>: One great idea is to create a surprise scavenger hunt. Hide clues around their house or favorite locations that lead to the surprise party. You could also enlist some friends and family to help decorate their home in a fun and festive way. Creating a fun playlist of their favorite songs is another great way to create a memorable birthday experience.
