Another one that you lost

I was in a Panera during a business trip. At another table nearby was a woman and her 2 daughters (nieces, charges, whatever, just going to assume mom and kids but I never heard them call her Mom or Aunt Maude or Miss Kim) who looked about 5 and 7 years old. The mom was way more patient than I am with my kids: no one was acting bad, just normal kids getting out of seat for no reason or upset there were mushrooms on the food, etc.
At one point the older daughter says “I’ve decided to be a vegetarian.” The mom asks “do you know what that means?” and the daughter said something, I heard “no but” but the rest was mostly lost in restaurant noise.
The mom said “well, you like when we get meat-lovers pizza, right?” and the daughter says yes pretty emphatically. The mom replies “being vegetarian you couldn’t have that kind of pizza any more.” The daughter thinks for 2 seconds and says “I changed my mind, I am not going to be a vegetarian.” Subject closed, they go back to eating.
