I think the flowers were a hit! Sure she didn't gush over them or you, but she didn't have anything negative to say about them so mark that in the + column.
It is too bad that in the middle of the night after being gone almost 2 weeks she has to pick things to be angry about.
The LBS can definitely become the WAS, I've seen it on here often, and struggle to stay positive so I don't become one too.
