Bearings

Sometimes during summer school my father used to teach us (me and my sisters) on how to sew dresses. My father is a tailor and he owns a huge sewing machine built in 1960's which we have until now. I can make a simple-cut short style since I have no patience and interest in dress making at all. Many times I broke the needle and threads, and that will cause to pull out the bearings of the machine which makes my father anger and never teach me from then on.
