Isn't it funny how sounds can stay with you? Wilbur is fascinated with the sound of his momma's serger. I asked her when it was oiled last... LOL I wonder if I taught him that though. We were working on a Kenmore and the thing sounded funny to me. I commented on it when I was oiling it and it quit. Wilbur picked up on sewing machine sounds - motor sounds - bobbin sounds - other sounds. Some machines don't have much sound some sound like a freight train. I was using Tri-Flow that day and now he thinks Tri-Flow will fix anything. By the way Bob the Builder is no longer Wilbur's hero. He has figured out that Bob the Builder doesn't fix or DO anything. Real people fix and do things. Farmers fix and do things. He thinks he is a farmer now. Oh and he turns 4 on Thursday. Hard to believe.
