Please have sympathy for me. I have a brother who knows everything about everything and does not hesitate to explain anything to you in great detail. When I "butt in" to tell him I've known that since I was ten years old he scolds me tells me to let him finish. ARRRRGH He once went into interminable detail explaining to me that when buying shoes I should remember that the number refers to the length and the letter refers to the width. We are both in our 70s and it never occured to him that I might have figured that our several years ago. Lord, give me patience.
