Friend: Okay, the address is XXYY on Smith St.
Me: Cool, thanks. *enters address into Google on his desktop*
Google Now (on phone): Hey! I noticed you Googled for an address on a completely different device. Would you like directions there?
Me: Uh...yeah, actually. How did you know...?
Google Now: Shhh. It doesn't matter.
Google Now: Shhh. It's okay. I'm your best friend, right?
Google Now: I know everything about you, Jason. I'm your best friend, right?
Me: ...let's go with "yes"
Google Now: That's a good boy. So, how about those directions?
