I think this "Love is silent, Romance is talkative." thing that Yusaku wrote is true, and a brilliant way to describe the difference between Love and Romance. Just like what Dr.Armstrong said, there are words that need to be shared. There are times you need to listen to what the other person has to say.
In fact, I know there are tender words that sends me warm shimmers down my spine and make me feel like a spineless jellyfish:)
Sometimes we need words to expess our feelings , and to let the person you love know how special they mean to you.
