Men and women very much like me are taking up arms in the Ukraine and fighting against the invader.

It’s one thing to see that kind of thing happening in the undeveloped parts of Africa or Asia and know intellectually that these are people just like me. Quite another thing to see it happening in a developed, European country.

I do not take for granted that I have the courage to do what those men and women did. I think knowing about myself is part of eventually having courage, if courage is necessary.
