Yep, pretty much how I am. My parents home, so they can smoke inside all they desire. Does not stop my clothing smelling like it though sadly. I think that was an issue a few times in high school and even at my first job. Got asked if I smoked.
@Ravenfreak was just talking about visiting his parents and doesn't live with them.
If you live with them and cannot escape being around their smoke 24/7, its a different situation. You are involuntarily getting your health damaged from the 2nd hand smoke and and they making you smell bad. They should do it outside.
For example, I smoke weed on occasion but I do it outside or in the garage when my daughter is here. The only time I do it in the house is when she is staying at her moms house. Of course it is my house and she is an adult. Technically I can do whatever I want, but I still think its wrong to smoke weed in the house when she's here.
