I've had soooo many cases of FedEx delivering my stuff to one of my neighbors. I do occasionally get my neighbor's packages too. Even though we all have well labeled houses.
Additionally FedEx does shit like give you some reasonable shipping date, then it gets delayed by 2 days, then when the delay ends up being only 1 day, they pat themselves on the back for an "early" delivery. The math ain't mathing bro.
