When my son was younger he would become so annoyed at the sound of someone eating that he could completely ruin a family dinner for everyone. At age 15 he is not quite as sensitive unless he is extremely tired, and if that is the case ANYTHING could set him off. He also can't sleep well if it is raining, can hear a motor running etc. Any constant noise is irritating to him. WHY? Here is my belief: As an adult I was diagnosed with Attention Deficit Disorder as well as Obsessive Compulsive Disorder. Though not officially diagnosed I know my son well enough to know he has it too. We both can be insensitive ~ hardly aware of specific details around us, or overly sensitive ~ where we notice every little thing and can't sort important stimuli from the unimportant...everything gets the same amount of attention. If this concern is about a young person I would offer hope that they will grow somewhat out of it as they age, as my son did. If the person is an adult my educated guess is that obsessive compulsive may be at work. There are some great sites online for more info. Just search using OCD or ADD & see what you think!
