English grammar question

My wife and I are very sorry to hear your news. We both feel very sorry for you.

My friend is studying English and is stuck on one question, for me it's right but my English sucks so over to you guys.

She has to create a sentence replacing the brackets with a sentence containing either of, neither of or both of.

So for example

I invited Seitse and Robbie for a gay fun boy party, but (Seitse couldn't come and Robbie couldn't)
...[text shortened]... y thing I would change is 'both of us feel very sorry for you'.

Anyone have anything better?
