That little girl is just adorable and also lucky.
I have a mail carrier who often forgets he is supposed to deliver mail to the address on the envelopes. I have received mail for the people in the houses on both sides of mine and one across the street. I've also received mail for people on streets I never heard of before. If it's a neighbor I hand it to them the same day. Anything else I take to the post office and let them try again.
