No workaround....

A and B are friends... At least A thinks so. They meet because A wants to meet B. Not because B wants to meet A. A has lots of things to say to B. But B is in a different world altogether. B doesn't even think A will want to say something. So B goes on and on and on... giving A no chance to say whatsoever. A also makes no effort to say anything thinking B will understand one day, or maybe it's good B doesn't understand, or maybe B deserves better things to be said to B, or maybe because A is tired with all the previous efforts.
So when A meets C, A carries some extra disappointment and frustration... and that leads to frustration in C. And as you have rightly guessed, this chain continues.
But you can't blame B for all this. As B's behaviour is also rooted in some past happenings and is not 'intentional'!
In short no one is to blame, everyone is to suffer, and life goes on.. after all they say happiness comes from within and neither B can provide happiness to A nor can A make B smile. So maybe the best solution is not to say anything to anyone, do as one pleases and generally enjoy without hurting others. 'Without hurting others' conveniently does not mean 'doing what pleases others'. And in case anyone is silly enough to get hurt, laugh at their silliness or sensitivity. Or pretend to have not noticed.
After all accepting circumstances and facts comes in handy... for everyone. It especially makes others' life easy....
