Compliment?

Student:  "Mrs. A, you look tired today."
Me:  "Thank you."
(silence)
Student:  "I said, 'Mrs. A, you look tired today.'"
Me:  "I heard you."
Student:  "Why did you say, 'thank you'?
Me:  "Well..."
Student (interrupting me):  "I mean, it's not like a compliment.  You look tired.  You look like maybe you could put more make-up on or something.  You shouldn't thank me for saying that."
Me:  "What should I do?  Cry in a corner because you said I look tired?"
(silence)
Student (thinking):  "Yes."
