W-I don't know but every time I put on my shoes it hurts.
Me-Have you outgrown your shoes?
Me-How do your shoes feel inside?
W-Well......my toes hit the ends of them.
Me-Then your shoes are too small.
W-How do you know?
Me-When your toes are touching the ends they are too small for your feet. That's probably why they hurt.
W-Why didn't you say so?
