I have some very good Armenian friends, and this is a very solemn day for them. Nearly all the Armenian owned businesses I know of are closed today. I don't know if I should blame my secondary education (high school) or the fact that The Holocaust gets all the "press" for my lack of knowledge on this topic, but I never heard of this massacre until I was working in Glendale, CA (which has the highest population of Armenians outside of Armenia).
