I think you don’t or you refuse to understand that David isn’t as comfortable with social media than Gillian is, that he doesn’t want to encourage fandom freakout like she does, and doesn’t want to handle crazy fans, which he would have to if he did something like that. People (me) go crazy every time he likes a tweet mentioning her!
He has his own way to support her, more private and lowkey, and in the end, isn’t it all that matters? I mean, do you want him to support her for you or for her?
One year ago, he went at her play when no one was expecting him. He never talked about it publicly, never mentioned seeing it, even if he often mentions seeing other plays or movies or concerts in interviews. He must have told her what he wanted to tell her in private, it’s between them only, and it’s the reason why it’s so pure, unique and beautiful. I also think the fact he wore the pussy hat during all his tour wasn’t completely innocent when Gillian was promoting her book. He didn’t have to, but he did. If you want to see David supporting Gillian, you just have to read between the lines.
