Whether you're dating or friends with a quiet, unassuming person, never coax him into changing -- it's that simple. If you're simply not content with the person's personality, do yourselves a favor and part ways amiably. Press the other person too much to change and it can build feelings of resentment. The bottom line is this: We aren't wired in the same way--nor are we always inclined to change our temperament to appease others. It simply isn't fair to expect someone to reengineer her personality to your liking. In a friendship or relationship, we should accept people for who they are-- flaws and all.
