When I lived with my parents, my parents did smoke and I didn't have any problems, but that time my mom and I lived with my grandma, my mom had to smoke outside because my grandma can't stand to smell it so I got used to it and then when my mom and I moved out by ourselves, my mom smokes inside, it made me cough a lot and just can't breath good so my mom had to smoke outside, and when I moved out to get my own place...I felt so much better but every time I go visit my family it is hard for me because I felt like I am allergic to smokers because I kept cough a lot and couldn't breath good. They had to move away from me or go outside to smoke. I don't smoke and never smoke before in my life.
