I have a sentence, as following:
Obwohl sie schikaniert wurden, hätten die jungen Kinder, mit denen ich arbeite, freundlicher sein können, wenn sie mehr mit ihren hilfsbereiten Eltern gesprochen hätten.
Although they used to be bullied, the young children, with whom I work, could have been friendlier if they had spoken more to their helpful parents.
But was unsure on how to say 'which' in relation to the sentence, as in:
Although they used to be bullied, the young children, with whom I work, could have been friendlier if they had spoken more to their helpful parents, which I find sad
Would you use:
... das ich traurig finde
Or is there another way?
