The response of receptor cells to odorants is, like other neuronal cells, variable depending on the conditions. There may not be enough of the odorant to stimulate an action potential; scavenger enzymes in the mucus layer may breakdown the odorant particles before they have a chance to bind to the receptor; or the receptor activation may cause an alternative signalling pathway to operate, preventing depolarisation. Even if a receptor does depolarise, it will eventually become adapted to the presence of the odorant and stop reacting to it. This is why, on encountering a strong smell that initially overwhelms you, after a few minutes you will fail to notice it any more. However, if you were to suddenly take a sharp intake of breath, you'd become aware of the smell again; the action of suddenly inhaling odorant-laden air exposes more of the olfactory epithelium to a greater amount of stimulus, which results in more action potentials.(smell@Everything2.com)

Because your nose gets used to the stench, and you don't notice it. If you went away for 10 minutes then came back, it would probably smell bad all over again
