DC are 14, 12 and 8.
Situation 1: DH has 3 brothers but they are not at all close. No bad feelings or anything, they just live far apart and none ever think of phoning or visiting each other. They are always happy to see each other on family occasions. Now, one BIL lives abroad. He has 2 kids who are in their early 20s. We rarely see them (5 years since I saw BIL and 8 years since I saw the DNs.) My DC (and their other cousins have no relationship with them but know their names and always count them when talking about family.)
DN has been arrested for manslaughter following a fight. He's in prison awaiting trial. I haven't mentioned it to DC.
Situation 2: A good family friend has just made a suicide attempt. My DC like her a lot. We usually see her and her DH and DD every couple of months. I've told them that she is very stressed and sad at the moment and they haven't asked for more details.
So, AIBU to not tell them about their cousin and this friend or am I right to think they have no need to worry about prison, manslaughter and suicide at their age?
If you think IABU, how would you handle the situation?
