It's important to remember not to utter those fatal words, no more pipes! Consider yourself in constant negotiation as an extremely picky pipe buyer. That gives you a sporting chance of passing on pipes that you notice but have not yet fallen in love with. As dreadful as the prospect is, consider culling the herd every few years (every ten years? Would you accept fifteen?) Of course, when you go looking for the pipes you no longer smoke, you try them all out. We know how that ends. Another pipe? I'm thinking about it.
My last relapse was a Ben Wade straight billiard clencher, smooth with light stain, at my local independent pipe shop, after seeing it on a visit to buy a small order of bulk tobacco, appropriately Proper English. I was impelled both by the pipe, the price (the proprietor made the price tag to include tax), and my desire to support the shop at this difficult time in tobacco pipe history. That's my story and I'm sticking to it.
I can't count the number of times I've said that but it never seem to work. My therapist said PAD is the worst form of OCD known and one with no known cure so I stopped going and recycled the money I usually paid her to my pipe acquisition fund, content to suffer this affliction for the remainder of my days.
