Mom counted how many packs dad consumed in one month and we found out that he uses 10 packs of cigarette in one month. Though it decreases compare before he can use up to 1 pack per day but it is still bad for his health especially now that he is taking meds. He doesn’t want to hear advices from us anymore and said we just let him do it because he is too old enough. I don’t really understand dad’s principle in life. He never realized that we are just concern about his health.
