I was in a well known high street bakers at lunch time. The young man in front of me in the queue was pushing a buggy with a young child in it -- not a tiny baby but not really quite big enough to be toddling independently, maybe a bit over a year old.
He also had a large spliff which, before he was served, he tucked (still lit, I think, but I'm not 100% on that) into the hood of the child's buggy. Lit or not, the smell of weed was really strong.
Now, if he wants to rot his own brain, or what might be left of it, fine, go ahead. But that child had no say in the matter. And if the man is smoking weed so openly on the street, we can guess how much drug use the child is exposed to.
what did I do or say? Nothing, even though I felt quite upset on behalf of that child. What could have made a difference? What could I have said or done? What would you have done?
