I really enjoyed this! I felt like I wasn't getting all the references - never having indeed seen, let alone heard of,
Eternal Sunshine - but I thought it was a very neat short story indeed. I wasn't sure (which I quite liked as an effect) whether there was really an authorial stance on LifeTrade, it neither came across as "Yay brave new future" or "Sci-fi idea DESTROYS EVERYTHING", which are the two extremes that short sci-fi stories very often tend to end up at. For a lot of it I was sort of expecting the main character to choose to trade lives at the end; it had a sort of build of inevitability which was side-stepped quite gracefully.
