my uncle say i can answer for him now.
He say every uncle in every country will become old when they age. He also say fart is just a tag along term. So he say he is old fart.
He also say he does not mind to ride a bicycle and sing the bicycle song so he say he has no inferior complex. He say every human will have emotional problem. My uncle say he allow me to say one thing without his consent - i really find my uncle a rare sinkie genius uncle.
