Yeah, just remember that if people are polite to you only when you can be engaging enough, they are prone to reverting to their patterns when you stop being so engaging. I’m not talking about this particular girl specifically, but marriage is not something to be embarked on lightly and one can’t afford marrying someone whose basic politeness depends on being sufficiently interested. Chances are the same person will somehow always regard the spouse as a person entitled to attention and polite treatment by virtue of being a spouse, but chances are that patterns of ignoring and being less than polite will return when chemistry takes a dive. This is why Uncle Chev rambles so much about the importance of finding a polite woman.
