A tree??

So, I picked Maison up from school yesterday and we head off to gymnastics. She's in the back seat sharing tidbits about her day. Then there is a long pause... "What's the matter?" I ask. "I don't feel good." Panic sets in, please don't throw up in the car! Finally, she responds. "I have a froggy in my throat." I offer a drink a water but she has a better idea. "Maybe I'll just eat a tree and that will scare him away". Okay then!
