Not only that, but Sandy's treatment to the player is very friendly, "cheerful" and "carefree"... Hinting at a potentially great choice of romance. She also writes to us to "visit the desert sooner", as if she misses us or something! And she is single. A thing which her writing style even purposefully suggests/reminds to us! (and she is a rare beauty, near Haley's level, too)
P.S. Last but not least, she is the only NPC directly being friendly, upfront, to us. From the beginning of our interactions! This is what earned her, second place for me, instantly. No other NPC in the game is so open and well-receiving to us, from the get go.
