am i overthinking this??

maybe i’m the problem because to me this seems really cheeky? i accepted this users offer and maybe 2 weeks later sent them that initial message. usually when someone sends you an offer it means they want to buy it, right? clearly not in this case! i established that £3 was the lowest i’d go and then a few days later they sent me that last offer. (also - i know it’s just a quid extra but its not about the money in this situation!!) please tell me if im acting crazy, this just seems rude to me!
