suspire

(verb)

to utter with long sighs.

"I told you over and over again that the green bag was for recycling and the pink bag was the child's birthday present. What is the child going to do with empty milk bottles, egg cartons and newspapers?" she suspired, while rolling her eyes and wondering whether they could get the Barbie palace back from the recycling depot, or whether it had already found a new owner in a wide-eyed recyclist who was now puzzling over who would recycle a brand new Barbie palace still in its original, non-recyclable packaging.
