A Difference of Opinions

Trying on new glasses with Father and Mother yesterday. I put on a pair with black plastic frames. 

Father: You look like a PhD student in this. Very mod. 

Mother: Don't look like a PhD student. 

Father: I didn't mean it in a bookish way. I meant the kind that looks very smart and sexy. Like what's trendy now. 

Mother: But she's not sexy.
