Well aren't THAT a cute expression... makes it sound so... innocent...
I mean- how can something so small beautiful creature as a bird do any damage?
Well my dear, let me tell you that it indeed can make lots, and LOTS of damage!
'Why?' you ask?
The little bird TOLD you something, DIDN'T IT!?
But, what did it tell you?, well-
It told you something that you weren't meant to to be told.
