Americans on the bus

I was on the bus the other day heading to my language lesson. At one stop a couple got on the bus and I immediately thought that they were Americans. They did not look like any Macedonia I had ever seen. I could not hear them talking until I got off the bus, but I knew for certain that they were American when I saw their socks. Below are some pictures of Macedonia socks and one American sock. See if you can pick out the American.
