Do you know how it feels when someone blames you for something you didn't do? It is irritating, isn't it? And, even if you DID do it (and of course, you didn't, did you?) blaming does not help. When there is a problem, the goal is to solve it -- not assign blame. Claiming that it belongs to someone else might push it away momentarily but guess what? Like a whirling boomerang it comes whizzing back.
Shifting a problem is not solving a problem, and when it comes back to you (and it will) it's worse.
Why not get started solving the problem?
