I left Dark Souls alone for a while some time ago, and when I got back in I was tasked with getting on a moving platform in Blighttown. The first time I got on, as I was reaching the top, I disembarked, missed my stop and plummeted to my death (I was unhollowed so that's one humanity down the drain).
Then, as I hurried to my bloodstain, I missed a jump, fell down and was eaten by the local fauna.
This was around the time Skyrim came out and I was playing that constantly.
Let's just say that after that incident, I took a long hiatus from Dark Souls.
