This is an expression, which actually everybody wants and needs to hear. I think "I love you" can be expressed not only between beloved couples, but also between those people who just like eachother´s personalities, not depending on sex and the duration of their acquaintance. Sometimes, when I am in a very good mood I just want to say it to everybody who I like very much, without expecting anything back. And sometimes they do not know how to react and partly look strange at me. I personally think it is not superfluous when people would express it more often to eachother. May be we would then even have more peace on this Earth...:-) But why people are sometimes afraid of saying it?
