I have a group of school friends ( of 60 years) we started meeting up about 15 years ago again after a hiatus of bringing up our own families. 5 of us, one joined recently now she is semi retired. We have a whatsapp group chat to arrange coffee meetings Christmas lunches etc usually about 5 times a year. I couldn't make the last meet which is a first. The problem I have is that I put on the group chat about a challenge my daughter is doing for a breast cancer charity, it was a polite request to help with this good cause under no pressure All of them read it but not one answered, I would not be offended if they said sorry we don't want to support but I am upset they all read it and I had no response. I might add 2 very close members of my family had breast cancer so it is a cause close to our hearts. Am I being unreasonable to take a back seat from these friends? They are all very well off financially but I reiterate what they do with their money is up yo them it's being ignored that has upset me
