half-truth is only half-true... Not according to the person telling it.
Unless they are liars....... or have an agenda..
And who don’t?..
My experience is.... most wouldn’t know truth if they backed over it and tripped.. fell... broke their hip and cussed nasty words..
Agendas are pursuit of an end. Half-truths are a means. Everybody has an agenda. Some of them let the end justify the means.
