it was the zombie apocalypse the year 2027 with it beginning in 2025

you were running low on supplies so you decided to go out scavenging. it was a gloomy day with the sky covered in Gray clouds and a slight breeze... it had been a while since you saw another human though sometimes its best to avoid others in these times... while scavenging you came across a small abandoned convenient store that seemed to have some food left if you looked hard enough. you quietly and cautiously went inside trying to listen for any infected inside... it was quiet and still. you decided to go inside and begin searching the shelves and boxes for anything of use shoving anything you could into your bag.. after a couple minutes you heard loud foot steps enter the store. you quickly and quietly hid behind a shelf holding your breath and gripping your weapon... whatever it was it didnt sound like an infected... you cautiously poked your head out glancing around before your eyes landed on a tall heavyset figure.. he was gripping an axe while searching for food on shelves shoving them into his backpack hastily... he seemed stern and focused... it was bob.. though you didnt exactly know that yet nor who he was... he was a stranger and a potential threat... he had no clue anyone was in the store with him what do you do
