There are myriad types of courage, and they are all emerging in Iran right now.
Kurdish songs are sung, hair blows in the wind, people dance - and on the other, cowardly side, people are abducted, tortured and killed.
But the protests don't stop.
An image has been haunting social media since Sunday evening: a basketball team, 13 young women and girls in red jerseys, with ponytails or braided hairstyles.
In their midst are three trainers, they wear black.
Not an unusual sight - but it is a women's team from Iran.
And it is customary for women basketball players in Iran to wear hijab, which is mandatory for them even in foreign tournaments and games.

"Teach your daughter that things like gender roles are nothing but nonsense," wrote trainer Farzaneh Jamami, who posted the picture.
"Teach them that they are valuable and irreplaceable." People who claim otherwise should not be believed.
Jamami ends with a message parents should give their daughters: “Don't hide.
Get up, hold your head up and show them what you can do!
Tell them that you are powerful and capable, that you are a woman of freedom.”
Jamami, who has more than 16,000 followers, has since made her account private, but the picture and caption are still visible to followers.
Canco Canada basketball club, where the team pictured is coached by Jamami, posted a picture of the team wearing hijab an hour after the coach.
The picture shown before was "private", the official game afterwards took place with Hijab.
The association respects the "personal opinions" of its members, but these do not necessarily reflect the views and policies of the association.
But we will continue to support women's sport.
The image published by Jamami could be dangerous not only for the three coaches, but even for their very young players.
Meanwhile, thousands of comments of solidarity and encouragement have accumulated under Jamami's post.
"You are great," it says, in Persian, "Your courage is a lesson for all Iranians," or "Thank you for teaching our girls freedom."
