There are many more actions that you can do to be a bad cubicle neighbor but thats all we have for now.
There are times when you meet someone that is just hard to work with and that can be placed in the category of personality conflicts. There are people out there that their existence can cause frustration. From the tone of their voice, process of attacking projects or even the tone of their emails.
But, there are also the times when you must work with people that are hard to work with because they make it hard. They make it hard on you and on themselves without even knowing it. These are the clueless ones. Most of the time they are the ones that love to talk and not just the nice office banter of someone stopping by your office. They are the ones that like to make a 30 minute meeting take two hours and when you walk out the door (probably sooner than that) the realization comes that this was a complete waste of time and that the reason for the meeting hadn't even been discussed.
If you have to:
I feel your pain!
What can you do about it?
Take a look at your company. If they aren't doing well and this situation is encountered, RUN! The company might be lucky enough to limp along using outdated and poorly thought out practices but it won't get any better unless the change comes from the top.

Have you ever noticed that office noise can sond like finger nails one a chalk board through a PA system? I have.
The residents of my neighboring cubicles are such a joy to be around. The grunting with lack of volume control as well as no respoect for others phone calls is GREAT! I have to say that the sounds that are emitted from my neigbors are hard to drown out. I think that a white noise devise might be a good investment at this point.
Try leading a conference call with 20 people on the line wondering why they can barely hear you over the coughing snorting
