I smoke so hard that I often shake the ash into the ashtray. Seriously, a little neurotic. Even if the gray is short, shake it off. Most of your mental stress comes from not being able to treat things easily and grasping them too nervously. A lot of soot will be shaken off. Insufficient energy, the essence is very cautious. When there are non-smokers around, lift your cigarette. You are a very careful person.
