Kitten Shrieks

Brother was especially loud today.  We don't think what we did was wrong, helping the human get that ten dollar book certificate, but you should have heard the kitten shrieks and then the texts started popping up like crazy, demanding we cease and desist all activity at once.  Really, what is wrong with helping our human?  Is Brother afraid that if we're helpful enough that the human might start seeing a few feline flaws?
