I think he means that people notice that you are different from the norm in some way(s).
For example, maybe you speak a little differently, or say things most people don't say (not necessarily bad or inappropriate things, it could just be things that other people don't think about), or your body language/movement is different from other people? Maybe you don't pick up jokes or read between the lines as much as other people?
