OK, let's say you were a guy (perhaps a Former Altar Boy) who met a woman once, and then didn't meet up with her again, but stayed in touch through emails and chats, pretty regularly.
And you went away for the weekend to the Holy City of Cental Canada to visit your sister. And on your way home you sent a message to the afore-mentioned woman (not your sister) that simply said "I am almost back!"
Why would you send this? Come on, you mysterious male brains. Why would you send this to a woman you kinda know?
