I won't interrupt to burp my ABC's, but you get the picture. My whole family saw me as Hammy when they watched this movie.
One of the most important things I did when I first started dating my current girlfriend is to inform her that I have ADD. I let her know that though many, many people think that ADD and ADHD are just a bad excuse for bad parents that have kids act up in class it is definitely real. I warned her that I had a bad habit of interrupting and verbally running people over in a conversation, and that I was apologizing in advance and gave her permission to scold me when she catches me doing it. I promised her it would not hurt my feelings to point out when I was being rude because most of the time I don't notice until after the fact, at which time I usually feel bad and apologize anyway. I must have done something right, because it's been three years now and she has become an old pro at it.
I also warned her that I am fidgety, and I tend to make noises without thinking, especially if I have something in my hands to play with. A good example is my pocket knife. I have carried a pocket knife with me everywhere for so long that I can't even remember not carrying one. I use it on a daily basis at work for cutting open boxes or at home for various different tasks, and my girlfriend has used it to her advantage on several different occasions, such as when a friend or family member needs something cut when we are out of the house. She will simply say "Steve, I need your knife.", because she knows it's always on me. On the down-side of this, I have been turned away from entering places several times because I had my knife on me, so I had to run back to the car to lock it away, which always drives her nuts. I even threw a good knife in the garbage once at a theme park because the car was simply too far away
....anyway - back to the original point -
When sitting around the house watching tv or reading or just daydreaming, I will (without thinking) pull out my pocket knife and start fiddling with it by opening and closing it, opening and closing it, "snick", "clak", "snick", "clak", over and over and over. I don't think about the sound. I'm just keeping my hands busy, but I'm driving those around me nuts. My girlfriend has been really good about it though. She kindly asks me to stop when I do those types of things or she will place her hand over my hands so as not to embarrass me if we are in public, to which I will apologize and put the knife in my pocket. She has actually put my fidgety behavior to good use. Whenever we sit together on the couch to watch television and I start getting antsy, she will turn to the side and place her feet in my lap. I will message her feet for her and it keeps my hands busy. Plus I don't mind doing it. It feeds my restlessness, it makes her feel good, and to be honest it always makes me smile because I love to make her happy. She is a hairdresser and is on her feet all day, while I work in an office and sit at a desk the majority of my work day.
The one hindrance on our relationship that I believe is my fault, is that several of her friends don't care for me. They are polite enough, but I don't get invited out with them much. They usually hide my uninvitedness under "girls night out". The ironic thing is that all of the friends that don't seem to care for me are also friends that are divorced and single. I'm sure it's the easily excitable nature in me. I believe they may see me as boisterous and possibly pompous because of the verbal steamrolling I sometimes do when I'm happy. The fact that I am aware that I do it, and don't "seem" to be trying to control it probably makes me look arrogant. Of course, the friends of hers that don't care for me have never said any of these things that I am aware of, but I am using educated guesses at this point. I have lived with this condition my whole life, and I've seen friends come and go. I have tried to change. It's almost as if there is some sort of chemical imbalance that shuts down common courtesy for a split second after something strikes my interest. I always apologize after the fact, but most people don't seem to understand. They see it as someone intentionally throwing a drink in their face and then apologizing that their hair got wet.
Living with ADD isn't easy. As a kid people would chalk your "rude behavior" up to being a kid, but as an adult you come off as just rude. These are a few of the things I deal with in my day to day life.
