Discovering more about your friends can deepen relationships and create lasting memories, but finding the appropriate questions can be tricky. Be wary not to pose too many controversial or intimate queries too quickly in new relationships as this could make the person uncomfortable. Also don't force anyone into opening up too early; rather provide interesting questions that allow them to explore various aspects of themselves more comfortably.
Some questions can be more casual and be used during casual conversation; others can go deeper, providing opportunities to examine values and beliefs more thoroughly. By framing hypothetical scenarios as questions about values rather than personally divulged details, these may help participants talk freely about them without feeling pressured into divulging personal details they don't wish to reveal.
Some questions can be difficult to answer, so it is wise to carefully observe their body language and dialogue cues prior to asking them. Furthermore, it can be beneficial to prepare in advance by writing down or practicing your questions with another trusted friend in advance; this increases the chance that your friends will open up to and respond positively to what you ask them about.
