I've never understood why so many peep seem to think that putting non-food objects in their mouths and inhaling toxic substances is a good idea or even acceptable behavior in public. There may have been a time when it was considered "cool" or perhaps "sophisticated," but to me, it shows a lack of respect for one-self and fellow travellers.
BTW, I also don't understand why so many peep seem to think that treating their bodies as a pincushion to be festooned with tattoos and jewelry in various places is a good idea, either. <grumpy old man/off>
