I have no idea. I cannot remember picking out a pipe at all most of the time. I have 96 on a rack on the wall and more in drawers, but somehow I end up with one... all the time... different ones.
Sometimes, I will think, "I really need to smoke that custom
blah blah blah pipe," and then latter that day I am smoking it.
It's like driving... I must have done it... I didn't think much about it at the time... I don't remember much about the drive... but here I am.
I have to make a four hour drive twice a week, and I do remember selecting pipes for that. I usually just grab my deepest chambered pipes and toss them in my bag. Then when I am on my way, I open the bag and think, "look at that... I picked the good pipes."
Also, I don't remember putting my clothes in the morning, but before I walk into a store, I check... and "yep, got clothes on." Life is good.
