did not know how to   1   it.
        I was not that guest, but over the last ten years I have   2   three things from where I have been a
guest. Abby, I cannot understand   3   I took these things! I have thought over as to how I can give these
things   4  !
        I cannot do it openly and   5   that I took them. This is a small town, and I am well known here. If
just one of these people   6   about it, I would be finished.
        Abby, what is wrong with me? They are   7   unimportant things. I considered seeing an   __8   for
a long time, but should I be   9   going to an expert, it would be known in the entire town   10  . I am sure
thousands of people like me wish to have the courage to return   __11   does not belong to themselves.
Should I just wait until it is   12  , and then find a good chance to   13   the things in the mailboxes of their

        Help me! I’m eagerly looking forward to your reply!
                                                                                                                                A Guilty Conscience

Dear Guilty Conscience,
        Yes. It will make you feel   15   to tell your story, but it will not solve your problem. You need to

in   18   town or city nearby to protect your   19  . He/She will give you much help.
        Please   20   my advice, and let me hear from you again. I care.
