Lines DS19mo has come up with lately (excuse the focus on body functions, please):

To Grandpa in a cautionary, not reactive way -- "Don't pick your nose, Grandpa!"

Something that has been repeated often, complete with dreamy, happy baby eyes-- "I love nursing!"

Upon seeing a book targeted at young children on toilet training, at FULL VOLUME in a crowded bookstore-- "Look, Mummy! Little boy is pooping inside small toilet!!!"

After giving a flower to another little boy at the playground yesterday, DS was disappointed when the little boy didn't verbally acknowledge the gift. He pauses a second, eyebrows raised expectantly, then says "you're welcome". No response. He waits a moment before saying in an exasperated tone, "thank YOU."

What is to give light must endure burning.
