The USPS mail is crazy

Our fat lazy mail carrier, is borderline incompetent or just plain lazy.
One time last winter, when it was really cold, she stuck all the mail for the entire block in one mail box, because she was too lazy to deliver it.
My 60 year old neighbor delivered all the mail that was left in her mail box.
I complained about her to the local post master, which just replied, yeah we get alot of complaints about her....
