Attempt 2: Directly switching profile pictures.

We decided that in order to receive a strong reaction from our friends on facebook, we would switch our profile pictures. Afterward, we got a lot of confusion from our close friends we regularly talk to. A lot of comments about getting messages between us confused since our profile pictures are what we look to first when we're checking who we're talking to. However, we didn't get much response from many people outside our close friends.
