And all because I wheeled a wheelchair, and my two sons were walking and holding their girlfriend on both sides of their hands, and I was going with them and talking about snow and winter. What hurt this woman, I don’t know.

You described the problem yourself. Usually walking moms are either built in two or three wheelchairs. Or, like you, a wheelchair and a chain of three children.
At the same time, of course, the entire sidewalk is blocked and in 90% of cases nobody even tries to give up the road.
In good weather, it doesn’t bother. But in the snow or snowfall, when it is difficult to turn away or filled with getting into dirt, such behavior is outrageous. and honestly.
I haven’t started spitting in the back yet, but who knows what will happen with age :)
