2 friends of mine - friends with me but didn't really know the other even existed. Friend A had a job vacancy. Friend B was looking for work and was capable of doing the role, although I had never worked with her and so didn't know her in a professional capacity but she has always been an all-round good egg. I put them in touch. They both liked each other and a start date was agreed (casual p/t job, not in an office or for an organisation). All was ok initially but B apparently started to become unreliable and let A down in a big way ultimately. I kept out of it and didn't take sides, as they're both intelligent adults. As soon as they parted ways, they both dropped me dead. B in particular never said one word about it and cut all contact from that moment on. A said it just hadn't worked out and has been off with me ever since. I've known them both for years. AIBU to think that I did nothing wrong at all and they are both ridiculous?
