Did you know that each human being has at least one of  "five love languages"?  Everyone wants to feel unconditional and complete love.  And, one of the five love languages is "gifts".  Now, if you know your loved one's primary love language or even secondary love language, you are way ahead of the game.  For example, if you have a desire or feel a need to fill someone's "love tank", perhaps giving a gift to someone would greatly influence him/her especially if that person's primary love language is receiving gifts.
Have you had an occasion where you saw this type of relationship happen right before your eyes that you would like to share?
