It's inconvenient but safer to have all packages require a signature. If no one's home they take the package back to their depot and leave you a note to come get it.
At least that's what I do nowadays.
I even stopped my daily newspaper because someone stole it 5 out of 7 days weekly.
These kind of people make me sick.
I'm old enough to remember not having to lock our house up or our cars etc. What's happened?
