Sisko: I’ve missed your steamed Azna.

Dax: You must miss Curzon too…

Sisko: He was… you were… are… a mentor… another father to me…

Dax: This happens a lot to Trills, Benjamin. Sometimes, our friendships with other species don’t survive because of the changes…

Sisko: It won’t be like that with us. It’s just… a little uncomfortable right now…

Dax: I suggest you allow yourself to be comfortable with your discomfort.
