separation anxiety

I want to sell our electrical goods online, via Gumtree, because they're no good (well, not much good) in Canada. But there's some weird forcefield that is stopping me. I have listed the items, photographed them, made my peace with their departure, but somehow don't seem able to actually put them out there for strangers to buy. The hardest to sell will be the answerphone, which has an adorable message recorded by all three children several years ago. Everyone comments on that message. The children have changed but the message is the same.
