What a weird logic! You know, David doesn’t think, breath, dream Gillovny. He lives his life, with Gillian when they’re together and without when they’re not, but not everything he does, says or tweet has to be related to her. Same for Gillian, by the way. He tweeted a tbt because someone has told him it was a thing and he found it funny. That’s all. Let’s just stop trying to read too much into their tweets. Please.
