It is not a smart idea to be alone with someone you have just met. When arranging your first (or even second or third) meeting with a person, make it clear that you intend to meet in a public place and arrange all transportation on your own. It is also wise to advise a friend or relative where you will be. Do not let anyone pressure you into doing anything you are not comfortable doing. Err on the side of caution and all will be well!
