Quit cessation guarantee

I smoked and angered the girl, and she solemnly raised a series of questions about "smoking cessation". The expression was extremely serious. I also asked for a letter of guarantee.. I have thought through it. I know that smoking is for myself and The harm of the wife and the future bb.. Long-term smoking is easy to get lung cancer... It is even more dangerous for others to smoke second-hand smoke.
Decide to stick to the following points from now on:
1. Because the “smoking cessation” campaign is not a one-off event, the amount of smoke is reduced, and it is finished fighting for early cessation;
2. Do more exercise and don't give yourself space to smoke;
3. Don't give cigarettes to others, so that people don't commit me, I don't commit crimes;
