He is a lovely man who I get on with really, really well. But this morning he has been whistling virtually non-stop for 20 minutes!! I wouldn't mind quite so much if he was whistling along to the music on the radio, but he isn't. The 'tune' keeps changing and is nothing to do with what we're listening to.
I'm generally quite laid back, but it is seriously doing my head in - my right ear is actually hurting a little!!
I know I should politely say something, but I don't want to be rude and it happens so rarely I feel like I'd be making a huge deal out of nothing.
