I am over 21 and although a lady of leisure I would not call myself old. Age is a state of mind iam enjoying my present age of (must ask a friend) 64 ? But I feel more like 16, 26. With no responsibility for anyone except myself. I can do what I want when I want, sound like a teenager. Going to quilting classes and listening to their conversations they would make any group of teenagers blush.
Tell your friend there are no old people quilting. Look at the quality of quilts, they are young, full of new ideas and excellent designs etc.
