Isaiah: Grandma, can I take a cold lunch tomorrow?
Me: Yes. What do you want?
Isaiah: Can I have waffles in my cold lunch?
Me: They may not taste good. Waffles are supposed to be served hot.
Isaiah: Can you cook them cold?
Me: I can toast them and then let them cool off.
Isaiah: OK. Can I take ice cream in my cold lunch?
Me: No, it will melt.
Isaiah:But, my lunch will be cold.
Me: Ice cream will melt and become milk.
Isaiah: I like milk.
Me: The ice cream will melt all over and make a mess.
Isaiah: Oh. Because of the wrapper? You don't have a container for it?
(smart boy - he knows what a container is)
Me: Yes, it will melt and run out of the wrapper.
Isaiah: Ohhhhh... OK.
