Is it your hands that are small or your fingers? i.e. square palm and short fingers? Well if you believe that these attributes play a part in personality, just means you are a practical person vs people with long fingers who are more feeling.
My hands have square palms with shorter fingers but i got a big head which isn't good when finding hats lol. Only time I think about missing out on longer fingers is when carrying something heavy and wish they were longer to get a better grip. Other than that no one has said to me your hands look weird or whatever, so I is it just you overthinking others will mock you or has it happened?
