I read through this thread, and finally found what annoys me - you! Thinking you have the right to puff ye stinking cemetery sticks where other people have to smell and choke on the mess. Then, throw ye litter on the ground.
Ok, sorry for the little rant - no harm meant to you personally. Hey, I love us all here on this forum! But, I still don't like to have to put up with second hand coffin nails.
Great thing is their habit reduces their existence.
