When I pretty young thing comes and sits beside you at the bar because, "You smell like my papaw". And you are not insulted, but understand.
I had a young thing chat me up all night because the aroma of my pipe.
if your family and friends have an intervention because of your PAD and TAD....
and your wife has you commited when that fails because it's cheaper to have you commited than pay your pipe/tobacco bill.
When the UPS driver hands your wife your most recent Tad/Pad purchase and asks if this one is hers because he has been at your residence several times this week you might be a pipe smoker... (happened friday, four for me, one for her...)
