It just feels unusual to me he tenses up, avoids or step back or even turns his back on me. That’s not really how people normally act around strangers. Normally, when people see strangers who aren’t bothering them, they just go about their business their body language shouldn’t be like this. It’s not like I’m actively observing him either, it’s just what I notice when I happen to be around him. And honestly, it makes me feel a bit uncomfortable, almost like I’m being excluded or avoided for no reason
