I can't believe I just found this out. I've had "Send Read Receipts" turned on in Settings > Messages. Like everyone else (we all like to pretend we don't), I always have my phone on me and usually read texts right when I get them. Obviously, this is bad because a girl will see something like "Read 4:26 PM" a couple seconds after every text she sends you. And as you can relate to RP Theory, this makes it look like you are always available / overly interested in her. Just a quick tip I thought I'd share.
