Five postcards

Today I received five postcards from five different countries, all posted on the same day. They came from China, Japan, Germany, The Netherlands and the UK. I got them from total strangers who are also members of Postcrossing which organises postcard enthusiasts worldwide. I thought it amazing that regardless of the country and the distance they all arrived together. They seemed to travel faster than some of the Christmas cards that were sent to us which also arrived on the same day.
