Other then my mom, no, no one else has experienced anything. Of course, I am not one to have friends over on a regular basis, especially due to the fact that in-between jobs, my mom usually stays at my house. No offense to her, it's just that I (a single man in his early 30s) prefers to go over to friend's houses at those times .. im sure you can read inbetween the lines on that ;-)
The really strange thing about all this is that if you had told me five years ago that I would be in the situation I am now with the 'haunting', I would have laughed at you for I was brought up to instantly fear any sort of paranormal activity... now that it has happened, it is really not that big a deal. I am not frightened of 'it', and I do not consider 'it' a nuisance, so I find it funny with your use of terms like "bothered" and "exorcism". No offense intended.
It really is a mundane 'haunting', so to speak. I have heard of people who grew accustomed to a ghost in their house, who would joke with it, get it to turn on the AC or raise/lower it... it seems I have adopted that attitude. Only I have yet to get the ghost, if it is even that, to raise or lower the AC. And yes, I have asked :-). Incredible? Perhaps. But I am really accustomed to it.
