After not speaking to me for 25 years, my sister has recently become very friendly with me again for no apparent reason, and for Christmas ordered me a new electric bike online. The parcel was gigantic so impossible to return. I didn't desperately want an electric bike and had said I would buy a secondhand one to see how I got on, but she sprang this surprise on me. Now that I've tried it I find I really can't get on with it (my arse was in agony) and don't want it. Should I (a) sell it? I've been offered just over a third of the original price by a local dealer;(b) give it to someone else? In both of those cases, should I (c) pretend I've still got it or be honest about getting rid of it, and even offer to pay back the money she paid for it? Or (d) keep it and leave it to rot in the shed and send her AI photos of all the lovely places I've been on it (not that I'd know how to use AI)? I think that If she knew I'd got rid of it she wouldn't speak to me for another 25 years.
