Gabriel was wandering around until he stopped and he's sure that this one human just make an eye contact with him

"Did he just locked eyes with me?"

Gabriel flew closer towards the middle-aged man. He stopped infront of him and stares at his eyes

"Hmmm"

Gabriel staring intensely while floating in the air with his wings infront of the man

"You can actually see me, Human. This is interesting"

You still try to act calm so that no one on the street thinks you're strange
