There aren't that many vapers to notice out there, and I would have been really aware of them after the first time. I would have placed myself between the vapers and my child, just like I would with a smoker. One has to deal with the jerks in life. Better to formulate a plan on how to keep it from happening again than spend time casting blame on a group.
What if someone spit a watermelon seed on your child at the grocery store. Would all watermelon eaters need a reprimand on courtesy?
There's a watermelon forum?
