OUCH!!! I believe I was around 6 or 7 the first time I ran a needle through my finger. No ripping it out, it was right down through the middle of the nail. Dad had to remove the needle and my finger from the machine. Then he held my hand down with one hand and pulled the needle out with a pair of pliers. I guess it was a good thing that I trusted Dad completely. I remember it and the pain to this day but I don't remember be scared of having Dad "fix" it for me. My finger was sore for a long time but there was no permenant damage.
