Well, I did it just now.
A nurse who I worked with years ago visited my office for something finance-related.
I said to her, 'Oh hi person x, long time no see. Do you recognize me?'
She flat out did not recognize me. I couldn't really believe it.
I reminded her of where we worked, and a couple of the situations we were in ... she said 'Wait, I know your eyes ... yes I do remember!'
She was full of compliments and praise. It was lovely :~)
