This next part is complete bullshit and a cowardly rationalization.
Two times now, I have quit smoking yet spouse didn't. Both times I lasted about five months as a non-smoker. I just don't seem to be able to "keep the strength" when faced with it morning noon and night. If only he would quit too.
And this part is hopefully not complete bullshit.
Black market cigs are $20 a carton. I like to think of this as an opportunity to stick it to the man.
(Please don't flog me - I've done enough of that to myself.)
