Whenever Dan or Phil misremember something that happened in the early days of their relationship (that I only know about because they posted it on purpose), I get so charmed and overwhelmed by how much life they've shared since then. Obviously it's normal to forget things, assuming you're not constantly rewatching old videos of yourself. But the way they've grown into and around each other like the hazel and the honeysuckle until things that were so significant in 2009 are just taken for granted as part of their lives (here I am thinking of the Tonberry plush specifically)... idk, it's just sweet. It's a lot and it's sweet and I'm happy for them and happy they choose to share this with us.
(And then also at the same time I think some things they "remember wrong" are likely to be things that happened off-camera and it's fine and normal for them to have done things that no fan knows about. But the Tonberry plush cannot be denied.)
