I vote for lunatic
+1, cause I fall in that category.
I like to think of it this way, gather a group of people from various backgrounds that have 1 thing in common in a room, the talk of that subject is discussed extensively then several times other subjects arise and are discussed, at times certain sub groups break off and discus other subjects, some relevant, some just opinion, some humorous, some not, some member will leave and return later, but eventually the conversation leads back to the original subject that the group have in common, then the whole scenario is repeated, over and over and over...
Ha ha! Your mother smokes Mixture 79
that's a mean thing to say :rofl:
