Smoking habit

When I'm walking on the sidewalk, I always encounter some guy who is smoking in front of me, and the smoke is emitted into the air in front of me, I hate the disgusting smell. When this situation happens, I always speed up and pass the person in front of me to avoid his smoke.

It's a little bit ironic that I used to smoke too, for about 12 or 13 years. But I have forgotten how I quit the bad habit, it didn't seem to take much effort or time like many people do.

I remember that I had started smoking since I entered my college, it was also an ironic thing ha. Going to college didn't make me get better, but it made me develop such a bad habit.
