Realistically, "fine" almost never actually means fine, no matter what medium it's conveyed over. It's generally used as a passive aggressive way to say "anything but fine" and should probably never be taken at face value. Add a couple of extra vowels in the middle to make it "fiiine" and that's a whole different topic for another time. Bottom line, if someone (we're looking at you, ladies) tells you that he/she is "fine," they're almost definitely not fine.

Unlike "Fine," this one's pretty simple. If you get it, you're in (literally). Sending a winking emoji to your romantic interest is usually enough of a sign that you'd like to see the person naked, but starting off a conversation with one is a dead giveaway that you have one thing on your mind.

In our experiences, the shortened version of "Oh, I see" almost never leads to anything positive. This is the kind of thing that a woman will text you when she's pretending like she understands your side of the argument but really stopped listening/decided you were wrong several texts ago. Just know that if you get this text, you're probably already beyond salvaging that part of the conversation, so cut your losses, figure out what you did wrong, and pick up the pieces.
