Yeah, I smoke my pipe in the house, too. Not always, but usually. Nobody complains.
Of course, I don't complain about much, either.
Spending $20 on some pipe gear is nothing. In a couple months, I plan on putting down $500 on an S&S E-carb. Nobody is gonna complain about that either.
If you got your own checking accounts, and the bills get paid on time and a savings is maintained, why is it anyone's business how much money you spend on pipes, purses, or whatever you want to spend it on?
