Never Say No — Jean F. Capron

Betsy Marsh has had it with Rob Carney. She's told him over and over she's not interested in him, but he just won't give up! Things only get worse when their teacher assigns them to create a comic strip together, so Betsy lays down some ground rules. It's business only. No phone calls, no constant attention.

The plan works for a while, and their cartoon is a huge success. But Betsy's feelings about Rob are beginning to soften. Now she's sorry about the business-only rule - while Rob seems perfectly content. Has Betsy warmed up to Rob, only to find that he has cooled off?
