I'm not sure if I'm really Aspie, but my mom with a Masters in Counseling thinks it's very possible, and since you all make more sense to me on this forum than anyone else I've ever talked to, it's highly probable.
My handwriting is actually very good, but I'm left handed, and I like art. So, I do take my good old time to make it pretty. When I actually do write fast, it is okay, and only sometimes I can't make it out. I do a lot of things in that situations like educ8 or b4 or something like th@. When I'm really tired, I will fall asleep while writing and then the sentence makes absolutely zero sense like if I were going to say, "notify me when a reply is posted" it would come out "notify me whennn the baby is cleaning the dinner." On chalkboards (or dry erase), I actually do better right handed, and that is no where near as pretty as how I write on paper. But, I learned because of that, I can actually paint (pictures...walls too I guess) with both hands, and I do so when most convenient.
