Funny how today's younger set express their love for someone or something by substituting the word heart for the word love. "I heart you." "I heart this pair of shoes." "I heart that movie." The heart does represent so much. Probably to get far from being cheesy with the overuse of the word love, heart sounds more hip, and so now.
Words evolve. People evolve. I have no problem with the word heart. Whatever form or shape it takes, as long as love is expressed and felt then i'll take "I heart you" anytime.
