This emoticon literally means "heart" since that is what it looks when viewed sideways. In IM language though, it's a less serious way of saying somebody you "
love" them, or at least "care for" them. Even if you do really "love" somebody, you don'
t want to say it every minute and every day -- it gets old and
may even scare him or her. So, use "<3" for
normal every day conversations, reserving "love" during the times you really want the other to know you mean it.
