I've certainly had many instances of, "So what's in the package?" And even with DADT, wifey doesn't pitch any of my catalogs.
Here's an interesting thought, Redtea. I'm in a marital arrangement that had vows which sort of implies contractual agreements to be the life partner as presented at the time. Then the bombshell of CD shows up. A typical response is, "This isn't what I signed up for."
Now, my wife and I have worked through all of that and civilly reside with DADT and remain married.
But, in your case, you're an offspring. There were no vows or contracts. Only a wink and a twinkle. You are a 'this is what you get' entity.
So, why the DADT attitude to a parent? Is it a, "My house, my rules!" situation?
