There May Be Something Wrong With Me

Warning: if your opinion of Dave is already low, this sentence may make it subterranean, so proceed at your own risk . . . yesterday was the second day of my new Creative Writing Class (we switch at the semester) and one of the students wasn't quite in his seat when the bell rang, so I yelled in what i thought was a playful but slightly admonitory tone, "If you're not in your seat when the bell rings you're late!" and the student limped to his seat-- and I thought hmmm, looks like he has a limp and then got on with the class; later in the period we went on a "field trip" to the cafeteria, and the same late, limping student was the last one out of the classroom-- so I had to wait for him before I locked the door-- and I noticed that he had a brace on his hand, so I asked him, "Hey, how did you get injured?" and he quietly said to me "It happened when I was born" and then, in a humiliating rush of cognition, it all came together in my very stupid little brain-- he wasn't limping from a skate-park injury, he was crippled, and that wasn't a brace because he jammed his thumb playing hoops, his elbow joints were inverted-- and so I apologized to him about how I managed to put my (left) foot in my mouth not once but twice in a manner of minutes-- and though I said I was sorry, this kid must still wonder how he drew such an insensitive and cruel teacher for an elective  (unless perhaps-- and I'm rationalizing like a madman here-- perhaps the disabled student liked the fact that I didn't notice his disability and was just as callous with him as I am with everyone else) and the class, which is composed almost completely of sweet girls, must think I'm a complete lout, and so, to remedy these faults in my personality: I swear here in this Official Sentence of Dave (TM) to START PAYING MORE ATTENTION TO MY SURROUNDINGS AND TO THINK MORE CAREFULLY BEFORE I SPEAK.
