Many, many, many moons ago(yeah, I'm that old) when I was a teen ager, I loved to embroidery. I had the horrible habbit of sticking my needle in the couch cushion when I got up to do something else. Well, my Mom sat on one of my needles. OUCH!! I felt terrible and needless to say I never did that again. Poor Mom! I guess that's why I'm so very careful with my pins and needles to this day.
