For a conversational starter I have a list :

- Adjusting my chair - other people use my desk when I am not there, we have a large transient population, no problem with that but as a back pain sufferer why do they feel it necessary to fiddle with me chair every time?

- Rudeness - all too often people leap to conclusions and don't like the fit with their ideas so rather than discussing just go off the deep end, we should work together, a weak suggestion rather than none can at least lead to discussion and an agreed result

- People who don't like fresh air - too many office workers seem to like hot & stuffy which just sends me to sleep.
