When does Los Altos
High start today?
When does Zoë come
home on Friday?
Does Gunnar need to
leave for school?

User
⚙
My app
{“School”: “Crittenden”,
“Day”: “Friday”,
“StartOrStop”: “stop”}
Do a lookup{“speech”: “Crittenden
stops at 2:55pm on
Fridays”}
When does Zoë come
home on Friday?
Crittenden stops at
2:55pm on Fridays

24. Preserve and reinforce your persona by
engaging the user as a separate entity
