My dad hasn't told anybody else that he invited me. I think he thinks that if we catch them off guard, they'll be decent. NOT.
Also, I don't plan on ever bringing up my dad's conduct to him. "I'm sorry" isn't in his vocabulary. I just mentioned his conduct so you would know why I've been rather perplexed that he up and invites me to a picnic after shunning me for 18 months, especially considering how he behaved at the funeral.
It is possible that since his baby brother died he is reevaluating things and trying to reunite his family. My dad is 75 years old.
Oh, and his JW children DO see him as just bird food. He just can't accept it.
