I won't say no to help without seeing what my target might be. However, I will reserve the possibility of needing to do it alone.

[ Sherlock starts going to another without checking to see if the man is following. ]

As for your own task, perhaps you can speak of something you were once ashamed of in another time, like when you were a child. You don't have to be ashamed of it now, but it might be enough to complete the task.

[ Unlike Sherlock's, that task doesn't have a definite sign of completion, but he doesn't think a lie would satisfy whatever is triggered to consider it done. ]
