Yesterday my mobile rang. When I answered a woman addressed me by my first name and added 'you don't know me.' She then said, quite slowly, 'I've been watching you, I know what you were doing last night, and you're not going to get away with it.' I pooed my pants thinking some psycho woman was about to ruin my life. Turns out it was a mates sister who wants me to put shelves up for her. Please help me. I need to get revenge for this cruel trick.
