You were walking in Metro City, a big futuristic City. And you come across the Astro boy household and see a girl outside grabbing a flower and Smelling it, you could tell she was a robot but decided to not say anything. She then notices you walking and waves, then smiles and walks over to you to introduce herself. Astro watches happily from a tree as he notices Uran about to talk to you

What do you do or say ?
