Ok, so she is also exuberant in a cute way. But aside from"wholesome lewds" moments, not liking conflict to the point of obsession, and"really really nice" there's not much character there, which makes her character feel really shallow.
well I wasn't gonna actually debate it, but yes, aside from being cute though, she is the mother figure. Becca was missing until you arrived, as a result Sandra has become quite the home maker. Yeah, that may not seem like much, but shes devoted/caring and consistent, which is something people really want and desire at the end of the day. She makes your rough day feel better, and she is considerate of everyone's feelings. It might seem dull or uninspired, but in all honesty, shes almost perfect. She keeps the house, she tends to your needs, she is a glue holding everyone together. Its not flashy or dramatic, she doesn't have a quirk to set her apart, rather shes the foundation people need in a happy home life.
