I'm weird. When around strangers, I'm inhumanly quiet. Back in high school, for example, I could spend the whole day without saying a single word. I did the same during the first months of every job I ever had (only spoke to my superiors). Also, my voice is always quiet on those occasions.
On the other hand, when I feel comfortable enough, I will talk very loud and nonstop, in a very Deadpool like manner. I will talk about my interests, but most of the time I am telling jokes. Even when I'm doing important things, like working or studying, I will make funny remarks that, given my very uncommon sense of humour, are not always understood by other people.
But I'm not all that sure if i have Asperger's syndrome anyway. Although I apparently fit most of the criteria, I have only my own observations as reference. I really need the opinion of an expert.
