Plantman, I think we have had conversations kinda like this in the past. I know you are of Cuban heritage. Is your wife also? For a Cuban girl to be quiet is very unusual. Unless she was raised by old school parents. Sometimes it can be freaky when they are quiet because you know they are just plotting out some ***** in their mind.

IMHO, if you are concerned about the silence, nicely break into her crossword mode. Or invite her out for a walk around the neighborhood. Involve yourself in her quiet moments. Sounds cliche, but women really need almost constant attention. And for all you guys out there who think that your wife doesn't....get ready for bad news.
