I found myself surrounded by really old veterans wearing hats that said, "Retired Marine - SEMPER FI." These hats didn't appear to fit on their heads, but instead seemed to hover over them. At one point, I mistakenly tried to take the last box of crackers that a veteran also wanted. He started yelling, "I ran away from home at seventeen, lied about my age, and joined the Corps! I fought in World War II, Korea, and NAM! I have no cartilage in my right knee! It's bone-on-bone, but every morning I run six miles! I did not sacrifice my knee for this country to come here today and have you disrespect me at the commissary. Oooh-RAH!" I dropped the crackers and walked away.
