These are the contexts of the quotations tweeted from @sueannbowling between January 30 and February 5, 2014. All but the last are from Killashandra, by Anne McCaffrey.
“This assignment could be interesting.” Killashandra’s thoughts after she looks up the planet Optheria.
“Fidelity was an unlikely disease for her to catch.” Killashandra has always been rather free with her favors, and wonders if her association with Lanzecki has changed her.
“That any form of artistry might be limited by law was anathema.” At least to the Federated Artists Association!
“A genuine one-solution tragedy, where hero and heroine both lose out.” Killashandra is comparing her own romance with Lanzecki to an operatic plot.
“One can get too wrapped up in role-playing.” Killashandra has, out of boredom, pretended to be a student on the journey to Optheria. Now she is wondering why she is keeping up the pretense with another traveler.
“Something was to be said for the curtailment of natural ‘beauty’.” Killashandra feels that allowing rather ugly thorn bushes to take over pedestrian walkways is going a bit too far.
“There were some things he didn’t know or was just careless about, and I was able to use those.” Tourist Trap, by Sue Ann Bowling. Roi’s explanation to his father about how he managed to call for help, even though Zhaim was much the stronger of the two.
