I do know that Sheila loved her boys and gave them the love,hugs and cuddles that she,herself didn't get.
June was a good mother,,but left both Sheila and Jeremy very confused after she'd explained that they'd both been adopted. Probably without explanation,,and certainly there were to be no questions nor mention of contact with the birth parents. Both children felt unloved and unloveable.
June was of a nervous disposition and had problems sleeping,,and when she did sleep,,she was troubled by nightmares.
Not forgetting that nature dealt a devastating blow to June when she wasn't able to give birth. A dreadful blow to any woman,,and one that I don't think June ever got over. Seeing her own sister with two healthy children,,then Sheila with her boys must have all added to her already fragile state of mind,,and the last thing you need is a " round the table conference " on the future of one daughter and two grandsons.
What about June and Nevilles' future ? They were getting on in years and everyone else was thinking about themselves. Who would have looked after their welfares ? Nobody ,,it would have seemed.
