People who are born under a water sign tend to be sensitive to emotional vibrations. They may instinctively recognize emotional cues, knowing when to make a move and when to play it cool. Water signs also tend to be deeply affected by the emotions around them and in extreme cases may present as psychic vampires. Water signs also tend to have difficulty maintaining emotional and relationship boundaries. Water people often seem aloof when you first meet them, but make thoughtful, affectionate friends once they get to know you.
