Of course we choose what we hold onto, but if there are some real bad times within our own family, then it remains with us because it's difficult to forget them. And most of the times, we get the setback from our own family members, because we are highly attached with them.
I think there is a big difference between minor inconveniences and true bad times in a family. Perhaps it's just perspective though. I think problems seem a lot bigger than they really are when we are younger.
I think, the emotion is bigger than the actual problem when its inside family.
Yes, that is likely quite true!
