What would make you get rid of a friend?

We talked about this in class the other day and I found out the answer this past weekend.. Risk. Ever play this boardgame? I played it for the first time the other day with my friends and that was a huge mistake. Unlike other boardgames you tend to take Risk a bit more personally. When your friend takes over a continent that you have held on to for the entire game after already playing the game for hours, you just lose it. The frustration level of this game is very high and it leads to friends screaming at eachother over a silly boardgame. If you have never played this game before then take my advise and play it with complete strangers.
