I shook hands with this older guy, customer at work today and he tickled my palm with this finger. What does that mean?

@bijouxbroussard: aww, he may have been a kindly old gent 👴

@justJett: Is that how [b]you[/b] shake hands with young girls ? 😲

@bijouxbroussard: It's my arthritis that has one of my fingers curled up towards my palm. People always get the wrong idea. 😬

@justJett: Hmm...🤔
