Suppose Alice and Bob were best friends who lived next door to each other. They had known each other since they were kids and spent all their free time playing together. One day, Bob's family had to move to a different city for his dad's job. Alice was heartbroken to see her best friend go, but they promised to stay in touch. Months went by and they talked on the phone every day, but it just wasn't the same without having Bob around. Alice missed her best friend terribly.
Can we infer that "Alice and Bob lost touch completely after Bob moved away."? Yes, no, or maybe?
