We need change that builds, rather than destroys. That means controlling arms supplies as the Arms Trade Treaty already requires governments to do. It means offering a refuge to those fleeing violence and persecution, as the Refugee Convention has for decades prescribed. We must also develop a Global Compact on Migration, to protect migrants, so often as vulnerable as refugees, and to manage migration for the benefit of all. If the terrible events of 2016 are not to be repeated, the calls for change to make the world more secure and inclusive must be heard and acted on. Nadi's experience may seem a million miles away from ours but we share the same thread of laws and norms that are supposed to keep us safe. Ultimately we are all in this together.
If we all do something, anything, each and every day to show that hatred and division will never rule in our own lives, this mountain of small and arguably prosaic acts of humanity, cannot but inspire others to follow suit...and then, maybe then, Trump will be rendered impotent and will get back in his box.
There are occasions when I find myself wondering whether some of us are too compassionate for our own good. We feel things deeply and we're affected to such a degree that we can't comfortably partake in activities others take for granted. For example, there are particular films which for the most part, we avoid.
Impossible choices are being made every day by more than 125 million people affected by crises and natural disasters. In fact, we are in the midst of the worst large-scale humanitarian crisis of our lifetime. Not since World War II have more people around the world been in desperate need of assistance as a direct result of ongoing conflict and violence.
It occurred to me that when he had got on the train, he instinctively gravitated closer towards me, another human being, to share his evening. We humans are social animals, and contact with others is very important to us. Having sat down opposite me, he ate his dinner and enjoyed his daughter's laughter in my company.
What do you think the purpose of education is? If you agree things need to change, what will you do about it? Whether you're a headteacher or a class teacher, at any stage of education, whether you're a parent, or a pupil, you have the power to make a difference in the small daily deliberate actions you take.
