Did You Say Slow Mail?

On 23 August 2017, I put 15 postcards in this Greek mailbox, addressed to different countries. For some premonitory reason, I asked to my partner to take a picture.

Any of the postcards arrived. I thought it was my fault, because, as you can see, the picking hours were not written on the mailbox. But let me say that it happens often in small villages in Greece (also in Spain), and the mail usually arrive.

I wrote to Elta Post some months later, and they replied that they could not assure anything about non-registered mail. I even sent a postcard to the postal workers of the village. Nothing happened.

Then, two days ago, one of my friends received the postcard. She was confused at first, and asked me if I had recently travelled to Greece. Then, she looked at the date: the postcard has taken exactly 13 months and one day to reach its destination. I wonder if the rest of the postcards will arrive/have arrived too.

So, please:

1. If you get a Greek postcard from me, dated in 2017, let me know.
2. Never give up, concerning to sent mail!
