My grand daughter decided that she wanted to learn to use my sewing machine. So I sat her down , taught her to thread the machine, and how to sew a seam. She was using scrap material, but when she made a wide seam and then made it the regular size, I proceeded to try to teach her how to use the seam ripper, and to reinforce the idea that she needed to repair any mistakes she made as she went. I went into the other room for more material while she was ripping out. When I returned she was throwing it in the trash. I asked her why, She replied, " Grandma it's only scrap material, and it needed to be in the trash,." " But I was trying to teach you how to use a seam ripper, and repair your mistakes," I replied. She said," I did learn how to fix it.. I put it in the trash."
