WIBU to bludgeon my colleague? She has been half humming half singing all morning. The thing that gets me is that she picks out a line out of a song and hums or sings over and over. sometimes there is a break and then it starts again, so now when she stops i am on edge as to when it will resume. I don't know what song it is as it is sung/hummed badly. I am considering that the incident report and health and safety review might be worth the "accident". or else i could just be hormonal (pregnant) and cranky, would it drive you mad?
