Should lullabies stay in chests? Let's get them out of dusty chests with our kids. Let's learn and tell our own and other countries' lullabies city by city. Then let's send the videos we took to each other. Let's listen to the different and beautiful lullabies of our cities, the lullabies of other countries and fly together to peaceful dream countries. Let's not forget to take pictures of our grandmothers with us.
