Before I crossed the front of the lady by the street I noticed that she had raised her phone at her eye level. Oh, someone is taking a street shot. So I understandably turned aside, at sideways glance I saw her making a charming smile. But when I was crossing her backside I received a cold stare.
Alas,she was taking a selfie! That charm facial expression wasn't to me.
I always get in the way.
staring, implies, looking, with wonder and impudence; gazing, with wonder and respect.
