Soooo... say you have a friend of the opposite gender that you met in college. You hung out a lot, but never really went "there" for various reasons. Fast forward to the interwebz age, some 15ish years later, and you find them on facebook. This is someone who's never been overtly emotional or expressive. Yet, after chatting occasionally online for a few months, they start signing their notes with "Love You" or " ♥ " or whatnot. What does it mean?
