3. Cake

A: Tomorrow is my son's birthday!

B: Are you going to bake him a cake?

A: I was thinking about it.

B: What kind were you considering?

A: That's what I'm not sure about.

B: Well, all kids love chocolate!

A: That's true, but it has a lot of sugar!

B: Why don't you make it plain vanilla?

A: I don't think the kids will eat a plain cake.

B: Then mix them and make chocolate swirl cake.

A: That's an amazing idea!

B: Another good idea is to let me lick the frosting bowl.
