You weren’t round the table that night so you have absolutely no idea what was said that night. By making statements like that you look stupid.
From the moment those twins were born they were precious and Colin was responsible for every part of there wellbeing.
He knew there mother was suicidal (was having very serious mental health problems) yet he handed his twins over to do god knows what that weekend.
He failed those children and he continues year after year to deflect his failings onto Jeremy
I think the quote from Matthew 7: 5 may be apposite here:
Thou hypocrite, first cast out the beam out of thine own eye;
and then shalt thou see clearly to cast out the mote out of thy brother's eyeAs for Colin knowing Sheila was suicidal, this is supposition on your part.
He deflected his failings as caregiver onto Jeremy, the bloke who killed them. I'll have to think about that one.
