Free groetjes

Yesterday I got a small present at a birthday party: a whole collection of return envelopes!

[ so I sent seven companies my kindest regards (groetjes)... ]

Return envelopes, just sent them back for free with some of your kindest regards...

All I have to do now is post them and my 'groetjes' will be transported to places such as Hillegom and Apeldoorn...
