This is a warning from the sewing gods.
I, of course, did what your never supposed to do; I let a pin get caught under the presser foot and hit it with the needle. Luckily, My machine seems to be totally fine since the emergency shut off kicked in before anything catastrophic happened.
My boyfriend (a physicist) marveled at how unlikely it is for me to have a small pointed object land perfectly on a small cylindrical object just right for it to bend and not simply slide off.
I know, I know, you're not supposed to let pins fall under the presser foot, but I have a tendency to sew seams super fast and remove the pins super quickly without stopping the machine. Well, I think I've learned my lesson.
