The post about a mother crossing the road with a wheelchair and leading the other hand of the second child to pain reminded me of my own life three years ago. Every transition turned into stress. Because the borders in the area of the zebra were no less than elsewhere. It is approximately 30. It was hard to lift the wheelchair with both hands. Not that alone. And I even measured this edge with a roulette, and photographed, and wrote complaints... and about the WONDER, three years later, when the children grew up on this dumb transition, the edges were cut.
