I'm probably saying nothing new here... but I'm going to say it anyway.
I've noticed that Zoe really thinks she's 'special' - as in she'll often say 'Does anyone else get this?' or 'Is it just me or...?' and Alfie often responds with 'I think that's really common'. He did it in today's vlog about drinking. She always does it when she's describing the most mundane thing.
A vlog of hers from 18 months ago autoplayed after today's vlogmas and she says 'I get this thing where I look at a photo and am just transported back to that time' and like... that's the magic of memory, Zoe.
Also, again, nothing new but her obsession with constantly looking back at the past is beyond nostalgia. Nostalgia is enjoyable for most people, it's why so many ads use it etc. But for her it's pathological. I mean, Alfie had a lovely childhood (or so he's said) and he's not constantly trying to recreate it down to the programmes he watched as a kid etc. It's so bizarre.
