"Their lawn, extravagantly watered, is a brilliant, almost unearthly green." (pg. 47)
Laura's lawn represents the way she feels about her actual life. Everything seems perfect from the outside-- she's married to a nice man, has a nice son with another one on the way, her home is nice and her life is simple. However, Laura feels like an outsider in her own life. Everything she doesn't feels fake and unnatural to her. Everything is too tended to, much like the lawn, and therefore not genuine or true.
