Fitzwilliam's Confession

Today on one of my walks, I ran into Colonel Fitzwilliam.As we were walking back to the parsonage, Fitzwilliam told me a thing of great importance. Apparently, Darcy had the pleasure of saving Bingley from a disastrous marriage. I know I shouldn't be surprised to learn that Darcy was the one who caused my sister's misery, but i didn't believe he was that ruthless to do such an act. And how could he deprive his true friend from love? I can't help but think that Darcy did this only for himself. He probably could not bare the thought of having a friend who was associated with our family! What a cruel creature!
