Avoid sharing too much of your intimate life with others, especially people who are new in your life. If someone you don't know very well asks you a personal question, don't be too specific with your answer. Stay general and vague about what you do in your free time, where you live, and even your marital status. It's not that you need to be unfriendly, it's just that you need to keep the boundaries clear until you know more about them.
