friends list

Your picture will disappear from their friends list, just as their picture will disapper from yours. Eventually , they will notice.
And then they will form a mighty pack of blood thirsty vigalanties, decend upon Cambodia, and smash & pillage until you are found!
if i remove somebody in my friends list, will he/she be notified that i did removed him/her from my list?
