I was wondering if you could help me with something.
Sure, anything you say.
Actually, it's a little bit silly.
Don't worry about it, just ask.
What words do I need to know to buy a pair of shoes?
You need to know the type of shoes you want.
Don't worry about that. I can point it out in the store.
The shoes can be comfortable or not comfortable, too wide, too narrow, or just right; and long or short. In girls shoes, the heel can be high or low.
Let me write all that down. I'm going shopping this afternoon.
