If you can recognize shit tests for what they are, you're miles ahead of the game. However, it's still very possible to mis-read a shit test, for being an actual question disguised in girl logic. Being almost 30 years old, I've realized there is a difference. If the subject matter concerns her directly (i.e. indirectly asking about if you're seeing anyone else), she's literally asking who else you're seeing in a girl-logic sort of way. If you agree and escalate/ignore, you'll probably just piss her off. It's not a real shit test. Everything else not having to do with her directly is usually a shit test.
