Give yourself a break. It's not your fault.

The more you experience these things, the more aware you will become, or may not.

It's a crap shoot if I can recognize it or not in a timely matter. Sometimes I ask friends what they are 'seeing' and what they think. A true/good friend can be honest, and those are the ones I listen to. Some peeps just don't want to hurt my feelings. [Which it wouldn't.]

Best wishes.
