You can't go by what a girl says, when she's giving you the devil for making a chump of yourself. It's like Shakespeare. Sounds well, but doesn't mean anything.
The quote highlights the idea that a girl's words should not always be taken at face value, especially when she is expressing frustration or disappointment. It suggests that her reactions may stem from her feelings about the situation rather than a clear communication of her thoughts. This observation points to the complexity of human emotions, particularly in romantic contexts, where people might say things in the heat of the moment that don't reflect their true feelings.
Additionally, the comparison to Shakespeare implies that while the language might seem poetic or meaningful, it can often lack substance or honesty in real-life interactions. Wodehouse cleverly emphasizes the importance of understanding the underlying emotions behind the words, rather than getting caught up in the surface language that might appear eloquent but is ultimately misleading.
