Oh you evil hussy, having dinner with a relative, how dare you!
If it were not for the fact that these clowns can cause you to be shunned by your family it would be funny. I think most normal people would be shocked that in 2013, in a civilized country, an adult person would be shunned by their family over having dinner with a cousin, because that cousin decided to leave a religion. It's absurd, only highly indoctrinated cult members wouldn't see how ridiculous it all is.
This is the problem with fading. Depending on your circumstances, it sometimes means you have to live a life of secrets, or else be constantly looking over your shoulder, wondering when you will get outed. Only you can decide if fading is worth it to you, you might be able to lie your way through the JC, but then you will have to live like that, pretending and hiding your true feelings, in the immortal words of Sweet Brown, "ain't nobody got time for that!"
I couldn't do it. My JW brother friended me on Facebook and I tried for a time to maintain two lists, one for non JWs, one for everyone else, but it was too much work, so now I send everything to everyone, whether it's my Halloween outfit, Christmas pictures or whatever. If he doesn't like it, that is his problem, he can unfriend me, I am fine either way.
Do what you have to do.
