I went all poetic with "I see myself in the mirror of night" - when you see yourself reflected on the inside of a window with the dark night outside, I thought - wrong!
I also know French and the Italian "di" also made me write "of the night". What a strange language sometimes. I hope Duolingo isn't wrong though...
It is a mistake in dictionary hints.
- vedere = to see
- guardare = to watch, to look at
