Drink up!

I ran into Jason downtown in front of the library. How are you? 

I have chapped lips, I need to get chapstick, and I'm so tired! he said.

Try this. I handed him my sippy cup thermal water bottle. He was drinking it enthusiastically.

Drink the whole thing! I said. I can get more! And I ran in and got more from the library water fountain. 

Drink up, I said, handing it back to him. Chapped lips means you're dehydrated and it can also make you feel tired. Can you whistle? If you can't whistle keep drinking! You look taller, I said, and your eyelashes are longer! We both laughed.
