Your father calls and leaves a message that your aunt died, only he named the wrong aunt. Funny or sad?

My dad called while I was out last night to tell me my aunt Reba died. After calling other family members to get funeral details, I found out it was actually my aunt Sarah that had passed away. I guess my dad got mixed up somehow because both women had been married to his brother. Reba was his first wife and Sarah was his current wife.

I can’t decide if my father’s confusion is funny or sad.
