Since Easter I have been battling a cough that has for the past 4 weeks included almost constant congestion. I have lost all sense of smell so am relying on family for things in that realm of which they have pointed out many- I decided to make a salsa for my oldest son to take to a party the other night- My husband came down from the up stairs and asking what on earth was I doing his eyes and throat were burning all the way from the top of the stairs- I smelled nothing. The point I'm making is when your sense of smell is impaired especially that of a smoker (which is proven) you fail to recognize what offensive odors are affecting everyone around you. Whether it is Smoke, cat, dog, rabbit, reptiles, rodents, heavy grease from cooking, it is only conciderate when you give a gift or sell an item that you take the utmost care to ensure it is just as clean as if you had pulled it out of a package in a retail store. We have at times bought sewing machines from people that were smokers which had been locked in closets or other places for years and yet when we get them in the car the odor is so strong we begin to cough etc. Smoke clings leaving a scum on evrything it doesn't just get blown out when you puff.
