ok so a few things to consider
we dont know what day it is, so we cant assume the child has to be in school. Could've been the weekend
BUT
the giveaway that its fake is the camerman's efforts to bring attention to the situation. "excuse me, do you see this? What is going on"...why would you ask another customer if you are just as puzzled as they are
Target usually keeps security at the door. Top Flight kind...this chick makes a dash out the store and people just look?
the "mother" gets noticeably louder as people approach trying to bring more eyes to the situation
the BIGGEST and most alarming thing is, its 2018, and people will do ANYTHING to go viral so i always assume something is fake unless its cited from a credible source
