I love simplicity and silence. I enjoy taking photos of birds. I also enjoy drinking tea — green, white, yellow, oolong. I live at Waikawa Beach in New Zealand, which I love, and strive to be an actively decent human being. Apparently the bizarre is normal now. Now 69, I'm super happy to be getting old — it means I'm not dead yet! 100% human (she / her). I joined the MB community on 05 January 2018. Follow me on Micro.Blog at https://micro.blog/miraz.
