If my memory did not fail me, I saw my father smoked a cigar once. He is not addicted to smoking, but he knows how to smoke. There was once, his friend bought my dad a packet of cigarette. Please do not ask me why, as I was too young to know nor ask at the age of six or seven. Together with that pack of cigarette, he gave my dad a cigar stick as well. That was the first time and the only time I saw my dad smoked one cigarette and cigar in a day! After which, he threw the rest of the cigarettes in the box away.
