This ninja is an employed welder, I have given him some small fabrication job in my shop..... I try engaging him in a conversation all he says is 'mmmmmh, eeeeeh yaaaah' even a topic to pass time he won't contribute much .... I wonder is it low self esteem or what is wrong ...? I choose to ignore him n ask myself how can u get help if u won't talk ata kazi utapata aje becoz I can't refer a Mumu man to a customer
