Dear Prof, Bitch,
I'm a grown up person. I know that this concept is hard for you to grasp, so I have little hope of you getting the next thing: for me, this means that I've accepted a lot of things about myself. One of these things is that I'm human. And humans make mistakes. Stupid mistakes. Idiotic mistakes. Really, really bad mistakes.
Now, I don't like to make mistakes any more than you do. But, as I mentioned, I've accepted that I'm going to make them, no matter how hard I try to avoid them. Hell, just looking back a week I can see about 10 things that I could have done better. But, hindsight is 20/20, and I can't change them. I can try not to make the same mistakes again, but, in all likelihood, I will in some cases. Because I'm absent-minded, because I just don't care, because I've not learned from my mistakes, because I'm stupid, pick your choice, but I will. And I know that.
Yes, working in the profession we do, mistakes can kill. I've accepted that as well. I can live with it. I can even live with myself if a mistake I made is directly responsible that some animal dies. I'm actually pretty sure I could live with my mistake having killed a human being as well. Why? Because I know that I can't change things that have happened, so I know I'd better deal with them and continue living.
You don't have to understand or like that attitude. But don't assume that just because I'm not giving much of a damn on the outside and deal quickly with it for myself means I don't understand what you're saying. I just don't see what more I can do than saying 'yes, it was my mistake, I know that, I'll try not to make it again'. I could have given you a number of reasons why I forgot to mention it. But they won't change the fact that forgetting it was my mistake, so I didn't, because excuses won't make it less my fault. And I don't think you were looking for excuses anyway.
If watching people flagellate themselves is your thing, it'd be much easier if could you mention that at some point so I could try to just get if over and be done with. Otherwise you'll have to deal with my clueless 'I said it was my fault, can I go now or was there anything else you wanted' face.
Incidentally, the dog I forgot to mention the platelet count was low, didn't bleed more than usual, had an uneventful, if long, surgery and was quite happily alive the last time I saw him. Thanks so much for playing that one up when everyone's nerves were worn because it was one of those days where nearly everything that could go wrong went wrong in the theatres.
