I would message you. Because I think I like you and that you're awesome. However, you're just going to delete my note without replying. I could write a tome based on your profile and all the wonderful connections and shared values we have, etc, but if you don't like my pix, you won't respond. So I'll have wasted 3 hours of my life.
On the other hand, if I go with the more efficient route and write a note that you think is too short, you'll assume that I did not make an effort. So you'll delete my note without replying. Again, wasted time. So I guess I'll visit your profile multiple times and wonder "what if". This is "online dating" as it applies to non-pretty (ugly) people such as myself.
I'm not looking for "friends". I'm able to find my way to the friendzone quite easily, thankyouverymuch. With no help whatsoever, I might add. It's a marvelous skill I possess. So you probably think this means that I'm looking for FWB or FB. That is false. It just means that I have no interest in starting off from the penalty box (friends).
