My other grandfather (not pictured) was too old and too near-sighted to join up, proper. At first. He wanted the Navy, but had to 'settle' with the Army after Pearl Harbor, age 35. Before the war he ran a Five and Dime called Kresge's, and had a college degree, so they made him a Captain and he ran a PX or two in Pennsylvania. My grandmother cried and cried when he got orders to go to Europe, but they were eventually rescinded. He left the Army a Major in 1954 and he lived through to the 21st Century.
I think of both of them, now, on Memorial Day.
