One of my neighbours just asked me to speak to another neighbour about access for works, because there is 'awkwardness' between them. I said no! Politely. But I did say no, on the spot without hesitating.
I said, 'If she has any questions I won't be able to answer them, if there's a difficulty of any kind I won't know what to say. I really think you are best placed to ask her, since it is a perfectly reasonable request.' And she basically agreed,saying there was this issue but she was sure she could brazen it out. I said,' I really think you can.'
I am normally quite bad with being soft, especially if caught unawares without time to think. So I am proud of myself.
