As a fellow Aspee, I've had my fair share of falls like this.
I'd have to say one of the worst was when I was doing a science project with another student. I sorta forgot what the project was about, but I wasn't able to completely understand the work. Needless to say my partner - whose name I'm not going to mention - got irritated with me and decided to work on it by himself, leaving me completely out of it.
As if it couldn't get worse, then the douchebag decided to throw me under the bus by making me present the project on presentation day by myself! I had no idea what the project was about or where to even start, and the fact that I was suffering from a bit of stage freight didn't help in the least.
Thankfully my teacher let me just turn the work in when he found out what was going on. We both passed, but he wasn't happy about what my partner did.
