THEIR or MY truth versus THE truth

[Alias Detective 1,085]

Is there a difference?

[Hardcore troubadour 11,543]

Yes. One is the truth and one isn’t. If you’re telling the truth there’s no need to claim it’s your truth.

Ultimate truth is elusive.  I say I have a thruth rather than the truth.

I began to wonder if its because of the pronoun situation we have now or if it is just a newer thing.
