the device is now vibrating and beeping because of the red dot that 's fallen into step a few yards behind me . i sat there helplessly staring at him , my heart breaking for him . as soon as they were out of sight , i ran down the street and did n't stop running until i was at home behind a locked door . were going to need some photos in there too . '' my eyes fill with tears , but i blink them back . it stopped me dead in my tracks .
