The etiquette of smoking

I am unfortunately a smoker and there is most definitely an etiquette to follow! Personally I always ask if it is ok to smoke when in company, I never smoke around children, I never smoke in someone else's home unless they light up first and that goes for in their car also. I also try to never smoke in mu own home if I can help it but always outside. I never blow smoke directly at someone either. It is our own personal decision whether or not to smoke but we need to be mindful that a majority of people do not smoke.
