Count it all joy . . .

I know grumbling and complaining is wrong and I'm not supposed to sin so that grace may abound, but please allow me a moment to grumble and complain so that grace may abound.
I'm brooding right now. Reason? Family.
I'm going to meet them tonight as they are coming down for a destination wedding that's not all that far from Chattanooga. I've had months to mentally, emotionally, and spiritually prepare for this, but I'm just not ready. You see, my step-grandfather is a professing Christian. However, you just wouldn't know it from the fruit of his family and how he treats his unbelieving children.
Everybody tolerates his "religious behavior", like having everyone pray before a meal. I haven't been part of this for a very, very long time. I'm growling (on the inside) at the thought of him making his unbelieving children pray before a meal. At this point, I have nothing to lose. Him and I aren't that close. I'd venture to say I'm closer to my new landlord than I am him. I really have nothing to lose. Because I have nothing to lose, I might actually say something. Something along the lines of "How 'bout we not pray? It's not really a group endeavor. Some of the people here only bow their heads, close their eyes, and wait for you to stop talking so they can eat. So, how 'bout not pretending? Let's just either be thankful to the Creator and Sustainer of the universe or not?"
Yes, friends, I have nothing to lose. I hope that my bark is not worse than my bite in this case. I hope I do have the gumption to say something like that.
