Thanks for the added explanation! German is my mother tongue as well and I also think "Bei diesem Bild habe ich mir nichts gedacht" is very elegant and basically not translatable.
I’ve grown to greatly appreciate those phrases that don’t translate. Admittedly, as someone who got competent in formal programming languages before I was ever competent in a second human one- it took me a while to appreciate the “syntax error”… lol.
Aber für Deutsch, brauche iche mehr ubung! :)
