also 4-D, eg. friendship; and 

MW: I think it is clear these map (basically) to relations in my terms. 

GH3&gt;	Except that you regard relations as 3-D ie. timeless and I do not.
As above, I can be a friend to Fred, but I may cease being a friend when he
double crosses me. (He may never have been a friend to me, but that's a
different issue regarding the vectorial aspect of friendship.) Again this
4-D. However the type of friendship is, in this case possibly camaraderie,
and that is again timeless.
