> **Iris:** For two or just you?

> **Me:** You’re always free. Where should we go?

> **Iris:** I don’t know, where do you want to go?

> **Me:** How about the [taco bus](http://www.seriouseats.com/required_eating/2008/03/cooking-with-kids-tacos-el-asadero-seattle-washington.html)?

> **Iris:** Great!
