I remember, when I was a child, I saw my grandfather smoking. It is said that grandpa has been smoking for decades. His old man often holds a cigarette in his right hand and takes a deep breath in his mouth, which makes him feel more satisfied and comfortable. Then, several white smoke rings were slowly spit out from his mouth, but they were sucked back from his two nostrils, so they went in and out like a dragon king smoking. Finally, thick smoke came out of his mouth again, and the air was immediately filled with pungent tobacco smell. I stood by and was choked by the "second-hand smoke" spit out by my grandfather. I quickly shouted at him: "Grandpa, stop smoking! Stop smoking! " Grandpa raised his hand, smiled casually, showed his yellow teeth inadvertently and said, "Girl, what does the film care?" I am in good health, what can happen! "Said, and pulled out a cigarette, alacrity to his mouth. Sometimes grandpa is a heavy smoker, and smoking more cigarettes will inevitably lead to grandma's complaints. "You ah you, alas, let a person how to say? How many times have you said "smoking is harmful to health"? Why don't you listen? "Grandpa still doesn't agree:" A cigarette after a meal makes the living immortal, and nothing happens. " While speaking, I went to vomit a smoke turn again. Later, when I was in the first grade, my grandfather coughed and frowned all day because he smoked too much. I know that if Grandpa had listened to our advice earlier and given up the bad habit of smoking, he wouldn't be so miserable now.
