The Sewing Machine China Whisperer
Image by mynameisharsha
My dad managed to locate this old man to get our sewing machine repaired/serviced as it was not working as intended.
The man you see in the picture is 85 years old, and he was a school teacher for the better part of it. Make no mistake, he knows everything there is to know about sewing machines. He patiently disassembled the entire sewing machine into its basic components, cleaned each and every one of them, all the while explaining to my dad their functions and roles, and assembled the whole sewing machine again. All this took around 4 hours.
I can only hope to be as intelligent and as active as he is when I’m 85 years old.
