Young children are interested in the idea of death, for example in birds, insects and animals. They can begin to use the word 'dead' and develop an awareness that this is different to being alive. However, children of this age do not understand abstract concepts like 'forever' and cannot grasp that death is permanent.

Well it was obvious from the start that the provision that TikTok either has to sell to a US owner or be banned means that some oligarch would be buying it. I suppose the broligarchs have been competing for who will get it. Sure, maybe some in Congress care about the security aspect, but underneath, that was mostly a pretext to get support for it. Would be nice if Tiktok refuses to sell it.
