I think the clue here is when Sisty88 says she normally "whizz" it through... Sewing by hand is slower than sewing by machine. I enjoy the peace I feel when I sit quietly and hand sew. If one is used to getting things done quickly then I can see why it would drive them crazy to slow down and do some hand sewing. I love the feel of the fabric, making my stitches small and even. It is one place where I can get away from the hectic pace the world around me is much of the time. If you have to have something done fast then hand work isn't for you.
