Stalk her online
It isn't sweet that you know where she's been for the past three weekends because you scrolled through her entire Instagram history. Women don't find it endearing when they're having a conversation and you interject by saying, "Oh yeah, I know. You tweeted it last night." You're a stalker, dude. Let her live her online life. You may think you're appearing interested in what she has to say, but be easy before you get blocked.
