OK... I am prepared to be flamed here but I am feeling fractious about this!
I work in a large open-plan office. There is my department, which is small and contained to a single corner of the space, and the rest of the floor is occupied by a different team who we don't have anything to do with work-wise. A new woman has just started on a desk just across from me, and she has the weirdest laugh I think I've ever heard. It's like someone is machine-gunning an elephant seal. It would be OK if it was just an occasional thing, but she seems not to have very much to do because she spends all day gossiping with the people next to her and then honking in amusement. It's driving me mad, not just the noise itself but the moments in between when I'm waiting for her to do it. It's very distracting!
AIBU, or would I be in order to say something?
