"That is not one of the things I am looking forward to."
Translation:To není jedna z věcí, na něž se těším.
Upon further review, I decided to add translations disagreeing in number between the head (věcí, pl.) and the relative pronoun (kterou, niž, sg.) to the recognized list. As always, thanks to our polite and respectful posters for encouraging course improvements!
I removed our prior comments inconsistent with the above decision and the secondary reactions to those comments from this discussion.
And please remember, if you cannot or do not wish to say it politely, you should not say it at all, at least not here. We will keep this forum as clean as we reasonably can.
