My favorite fruit is apples. Do you like them too?
Yeah I like apples. The apple tree originated in Central Europe. 
Oh really? That's interesting! Why are apples different colors?
I'm not sure of the exact science but there are over 7,500 cultivars of apples.  So they have been bred to have a wide variety of characteristics. 
Wow! That's a lot of variety! I like to use apples in baking. What else can I make with them?
You can make cider with apples. There are two types of cider: hard and soft.
