I'm new to TRP and finding it difficult to understand the concept of Shit Tests.

I read Shit Tests 101 from the sidebar, The Book of Pook and also a lot many other posts on that topic but still I'm not able to understand it fully.

Whenever I'm talking to some girl that I'm interested in and she says something that sounds completely normal to me and I respond to it normally too. Later I find out in some or the other Field Report or post in TRP that it was actually a Shit Test and I failed it by replying in the way that I did. I know I'm very BP'd right now and I'm trying really hard to improve myself and be RP'd. I've begun lifting 5 times a week and I'm also taking care of my diet. I just want to know understand Shit Tests and how to handle them.

I know its not possible to state all Shit Tests that men or women could throw at you but if any senior RP man could help a beginner by explaining this topic and the way to handle it, I would really appreciate that.
