Playing games?

<p>How can you tell if a guy is just playing with you and not totally serious when entering a relationship?</p>

<p>My friend asked me this, but I felt totally useless because I could only spout off a few things for her. What do y'all say?</p>

<p>Somehow I can't see too many people taking the trouble to "play" with someone on something like that.</p>
