From a sociological perspective, social norms are informal understandings that govern the behavior of members of a society. Social psychology recognizes smaller group units, such as a team or an office, may also endorse norms separate or in addition to cultural or societal expectations.
Sewer Odors in Bathroom. DEAR TIM: We recently have begun to notice a sewer odor from only one of the three bathrooms in our house. It might be the toilet, but it's hard to tell. The smell is not constant and some times it is very strong. Everything in the house drains fine, including the toilet with the odor.
It might smell sweet or foul. The most common complaint is ammonia-like smell. Basically, the odor arises due to the concentration of chemicals. When one's intake of water and fluids is normal, and the bladder is emptied at regular intervals, the urine is often clear and does not have any odor.
