Slow post

I sent this postcard from Rome to my mother three years ago when Pedro and I spent a holiday there.
Imagine my surprise when I opened her post box this morning and found it among bills and advertising leaflets.

I could recognise my hand-writing on its back and the strange stamp I had bought and stuck to to the postcard in the stall where I bought it. The man at the kiosk told me it was not the official mail, but he assured me it would reach its destination.
 It is true that he did not give me any details about the date of arrival!!

Please, believe me, this story is true!!!
You can check my dates in Rome here!!!
