history: I saw a child help another child across the street the other day. I saw a kid help another kid cross the street. It was soo cute. That's really cute! Were they the same age? One looked jsut a few years older. My children are getting older How old? My son is fifteen. 
current: Tough age. Are they doing ok?
next: Oh yes. I actually ordered him a Lyft the other day to get from one friends house to another. I wasn't worried though. I think the system is solid.
