This is all so funny!
Now the first post that started it all, lol! When you said you held your mouth "just right" I really laughed because I do that too! And I also obsessively watch the seam when I know the bobbin is going to run out.....also I've stitched merrily along never noticing that it did! Having to repin and resew is such a pain!
And I have removed a bobbin when it was getting low, and so far the quilting elves haven't come along to remove the thread for me. I haven't really talked to my machine yet, but it's fairly new so we're just getting to know each other. :)
