Quietly realising I did not, apparently, press record for the last segment of my truck tinkering today.
(Though I've heard others complain that sometimes GoPros will just decide not to record, despite the record button being hit, and you have to make doubly sure that it's doing its thing.)
Thankfully, I've got the most important 80% or so of my suffering on video, so now to just procrastinate on editing a video together! Oh I do so hate doing video updates, they're so much work to put together.
