The item to remove.
You should always call PrepareForWriting before changing the list contents. Otherwise, the list may be in process of delivering events and therefore the original is locked. Calling PrepareForWriting changes the input list to be a clone so that your Remove call can still work on the clone. If PrepareForWriting returns true, you might need to update any private references to the list that you maintain in other areas of your code.
