I still think it's kind of funny you got caught. You should always blow the smoke into a towel thats folded up and then spray like a little squirt of cologne or something and you won't get caught. That's what I do and I don't get caught.
And you have to make sure you put out the bowl, because that is where most of the smell comes from if you are using a doob tube (or "sploof") I used to be really good at smoking in my room, but I would still slip up sometimes, and my mom would find out, but she didnt really care, she just mainly was pissed that I would disrespect her for smoking in the house when she had asked me not to. I found that its much, much, easier to just take my bong and smoke on the deck. That may not be an option in you case, though. as you said, you were "pushing it" http://www.hipforums.com/newforums/s...t=349085&f=231
Or you just have no smell for marijuana. Its common, right after you smoke, that you wont be able to smell it very well. Thats how it was when my mom would bitch me out for smoking in the house, i thought I was all good, then my mom would come out and be laik "it smells like pot in here!"
...I smoke in my room all the time and just blow it in a towel. In fact I'm gonna go take some pictures to show you what has happened to the towel I use to blow smoke in lol. It's pretty funny.
