HOWEVER, have you ever been in this scenario in the supermarket? You’re attempting to leave an aisle and you can’t because the person in front of you is slowly, slowly, shuffling along, very slowly. You quickly think to yourself, this person is:
c) Back from the dead
If it’s a) and/or b), I’m happy to wait for you, please take your time. But both of these options can generally be ruled out rather quickly, even from behind. If it’s c), uh, then I don’t even care about ruling it out, no need for me to be loitering near any fellow shopper I even remotely suspect of being a zombie. But if it's d) then get the fuck out of my way!! Seriously! I’m not spending my whole night in aisle 6 so you can text "sup?” to random persons on your contact list that you have deemed most likely to respond!
