I’m a @duolingo user for over 5 years.

For the first time in ages I tried the Irish there.

The AI audio is atrocious and often incomprehensible. Shame on them for dumping the fine native speakers they had earlier.

A total embarrassment.

Black-and-white historical portrait of Dr. Aletta HenriΓ«tte Jacobs (1854–1929), the pioneering Dutch physician and women's rights activist, shown in a circular frame with a textured border. She has curly dark hair piled up, a serious expression, and wears a high-necked dress with elaborate floral embroidery on the bodice. As the first woman to officially attend a Dutch university and earn a medical doctorate in the Netherlands (graduating in 1879), she became one of the country's first female doctors. In 1882, she opened the world's first birth control clinic in Amsterdam, advocated for women's suffrage, better working conditions for women, the regulation of prostitution, and international peace efforts.

THIS STATUS IS JOY

I have confused
the letters
that were in

and which
you were busily
scribbling
for a book

Forgive me
they were a pale view
so sad
