I was talking to my mom about Nelson Mandela yesterday, & she reminded me that when I was a young whippersnapper, maybe around 17, I got her to write letters to the South African government to free him. She added, “we wrote one for that lady, too” by whom she mean Aung San Suu Kyi.
I don’t know how much letters do, but I do know that you feel like less of a schmo if you actually do stuff like this.
