Learning curve

I hate teaching. No, let me rephrase that - I loathe, abhor, despise teaching. With a passion.
I get very short-tempered and easily frustrated when I teach, especially when my "pupil" and I face a rather large language barrier. I've lately been instructing my father in the use of his new laptop, but every time I've sat down to help him with something, I always snap at him and leave with a headache. My own knowledge isn't so far advanced that I can "dumb down" the topic for him, nor can I revert to analogies or other teaching methods when they simply won't translate. So we've resorted to the "monkey see, monkey do" option, but it still leaves me aggravated.
I get irritated when people don't know what I know. It's no fault of theirs; I'm simply not patient enough to teach, especially not a subject that I don't particularly enjoy.
I shudder to think what I'll do when my children come asking for help with their geometry. >_<
