Because of the way I was brought up (saving milk bottle tops to buy guide dogs, cutting out used stamps to buy...well guide dogs again - heaven knows what the damn dogs are doing with all the stamps and foil, but my guess is mailing some kind of robot to the moon) I am quite fastidious about recycling wherever possible. When the zip stopped working on my coat, I just held it together for two years on the grounds that 95% of the coat was still doing its job perfectly well, and it seemed a shame to get rid of it. So the charity shop only ever gets goods of reasonable quality that could offer plenty of use to someone else, but because I don't want them I feel as though I am using the charity shop as a way of palming off my poor purchasing decisions on some other poor fool who has to store it until someone equally misguided comes along to take it off their hands.
Despite the fact that last week I saw a multi pack of women's knickers in the shop, I still feel as though a box full of unused stationery, some barely-worn clothing and an old picture frame is in some way inappropriate. Fortunately, my desire to de-clutter, when it does rear its ugly head, is so overwhelming it compels me to forget this source of potential awkwardness and sends me off undaunted to the shops complete with bags full of my crap straining at their seams.
