It's clear how your childhood ( I mean everyone here) is definitely very different from that of the children of today no matter your country of origin or globality (correct me if I am wrong). Not in any way calling anything bad but as a child I guess you were usually asked to leave the room when adults are definitely going to be having adult talks of whatsoever intensity?
Nowadays, the level at which children middle into adults talk is something else.
When adults are talking when I was still small, I don’t even have the right to speak, and whenever they having some sensitive discussion, they do always ask me to excuse them, so that I won’t have any knowledge about whatever they want to talk about. I feel things are changing already, and whenever adults are talking now, kids do involve themselves in the conversation which is not really proper, that’s why kids are being exposed easily now, they listen to conversations which they are not suppose to listen to.
Whenever I want to talk to my friends or family members about some sensitive things, I do always ask the kids to excuse us, and if it’s a place that the kids can’t excuse us, then I will move outside to talk about it, or I will just postpone the discussion till another time. Kids are not suppose to hear some things that adults are going to say.
