Parcel received by John (the UK). This piece of mail is one of the best surprises I have received by post lately. Not only because of the content (I loved it!), but also because of the thoughtfulness of the sender.
Some months ago, I posted four stamps belonging to this set. I wrote: "I would not mind to receive the rest, but I am not sure if they are still available." And then John stuck on this letter exactly the eight stamps I had not previously received.
Mail can warm your heart.
