These kids today

So we were at the park having a picnic with some friends and this little girl, about 6 0r 7 years old comes over to our table and says "where are the kids' drinks?"

"There aren't any" we reply, because besides what Gabe was drinking, there weren't. She gets this wide-eyed look and gives a frustrated grunt, then goes back to her own table. Her parents and their friends continued chatting, oblivious.

Then when we're eating our delicious sausages, she's back. "Can I have a hot dog?" she asks.

"No," I say. She gives us another look of disbelief, as if to say "how dare these adults refuse me what I have so rightfully demanded?"

So, my question is, if you're at the park with your kids, and your kids start pestering another group in a not-cute way, shouldn't you intervene and tell your kids to knock it off? This girl's mom did nothing.
