The reason for this is that we're dealing with Elly's wish that her children not remember any bad experience that they might have had with her. The sort of failure she and Val Stone are want to live in a world of make-believe in which only the times they didn't act like jerks should matter because of the fear of the evil, conflict-causing MAN concept of "accountability". The form it takes in wrining her hands about family traditions being lost is that the children are supposed to both ignore and forget the fact that, as an extension of her creator's will, Elly is landed with the belief that children should NOT be curious about the super-important things adults do nor should they intrude upon the physical and mental buffers Elly places around herself to compensate for her easily distracted nature.
This means that they are to be interested in something they don't properly understand and is more or less forbidden to them because their elders want both isolation and interest. Having to admit that yelling "Go away and stop bothering me or else" is a shitty way of keeping a tradition alive is unfair and wrong because it keeps a child woman from having her cake and eating it too.
