4 weeks is quite a time

I visited friends of mine today for tea,   
They are old school and send Christmas cards by mail.
This week they received a letter back that they had mailed two years ago to an address less than two kilometres away from their home.
It was returned to sender as they could not find the address... 
One kilometre per year is quite slow, I would say.
