A bit of near-sightedness

After I witnessed one of my kid's get up and walk closer to the board to look at a problem for about the fourth time today, I had this conversation with him:
Me: Have you ever gone to the nurse to get your vision checked? To see if you maybe need glasses?
Student: Yes.
Me: Oh, well, did they say that you needed glasses?
Student: Yes.
Me: I see. Did you ever GET glasses?
Student: Yes.
Me: So do you have glasses here at school?
Student: Yes.
Me: Can you put them on??
Student: Yes.

This is of course a TAG student!
