Hi,
I wonder how would you take the ‘Don’t eat yellow snow’ advice?
It’s meant to be humorous, though it is rather coarse, and is often sarcastic (stating the obvious.)
Or do you mean ‘what is the meaning behind it?’ rather than ‘how would you take it?’
If snow is yellow there’s a very good chance something/someone has urinated in it.
Well, it’s meaning quite obvious, I was wondering why it was given (= don’t do silly things\be wiser…)?
As I said, it’s meant to be humorous.
