Metal madness

I've been patient all week, waiting for stuff to happen, as slowly as it needs (it's always slowly when you're in a hurry).
Got the cylinder head back from the engineers yesterday, even got them to use a die on the other threads to clean them out properly, all nice and tip top shape.
The plan was to get working this morning. You cannot rush around most the day then sit down to mechanicals, thats how you break things. I prefer to wake in the morning, able over to the garage, and start on some easy stuff, like waking up. And so last night was my boy's birthday, he and his cousin kicked me away from the pc so i went and wandered around the garage a bit, you know, just looking. Looked at my shiny clean head on the bench, and the spark plugs lying next to, and thought to myself, this is the easiest spark plug insertion i'll ever do on my bike, since i'm apparently so freaking bad at it, i may as well practice.
And i'm glad i did, the other 3 holes took the plugs perfectly, but the one thats just been done, not even halfway, then stuck.
I don't know, i'm not any kind of expert, so i'll have to ask, when someone has a chance, and take it from there. This is where self control is hardest, and while i'm quite upset, it won't help to express it, it any way.
I guess i'll go read a book, that never hurt anyone.
peace and love
