Meet adorable Chloe, one super polite little girl.
Chloe's proud dad posted the video, with the message:
"Recently my daughter and I spent some time at the Copley Place mall in Boston, MA. My daughter took the liberty of standing at the escalator to say "bye" to everyone on the escalator.
"Almost everyone said "bye" back to her and had smiles on there faces. I just thought it was the most funniest and cutest thing. Hope you guys enjoy it as much as I did."
Chloe's wonderful waving has been viewed over 100,000 times on YouTube.
How cute is little Chloe?
