As a baby I was born with a pituitary issue which meant my hands and feet were abnormally small. They never grew that large at all. I can run and walk fine and they’re not deformed or anything, just tiny. I might have some weird world record for smallest hands and feet on a fully grown adult!
Yes that’s essentially what’s happened. And yes, definitely throws people off. Everyone’s hands inevitably swallow mine during handshakes.
An old friend of mine was born with two fingers and a thumb on his right hand. Instead of awkward left hand handshakes he just owns it and freaks people out.
