This is the thing - if you’re going somewhere you don’t need/want to mention, you just don’t post stories about it at all. It’s not hard.
But the fact he makes such a massive fuss, asking about hotels, posting maps, posting pit stops, and then posting when you’re back at home, shows that he wants to create this big suspicion. If he hadn’t posted stories yesterday after the football match for example, nobody would have thought anything of him not being online. He’s SO WEIRD.
