I work with a lady who sometimes uses an extremely irritating voice. She is very friendly, and I enjoy talking to her, but when she uses this certain voice I just want to pull my hair out. I try to get busy with something else but this seems to confuse her and she persists. The voice is high pitched and whiny. I think she thinks she’s being cute or playful when she uses it.
How can I point this out and ask her to stop without offending her? I would like to be subtle but all I can think of is ‘can you please not use that voice you’re talking with right now?’
