Talk to them, ask them questions about themselves, share stories, make them laugh, but do not pry into intimate details about their life. Keep your emotional distance and they will be attracted to you. Easy. Suggest an outdoor date, something wild and wacky like floating on a boat down the river then having a picnic by the riverside, anything. They love activities. These are the easiest people to get a date with but don;t think that this is written in stone, they are the biggest commitment phoebe of all zodiac signs. Enjoy the time you've spent with Sagittarius and be prepared to move on or at least share them with others because they will be doing the same. All in good fun.
