...Janice keeps saying this. I remember Gary "Honk" Busey kept saying it too. Is this an Americanism or is it something you get taught in therapy?

No idea.

But I suddenly feel the urge to HONK!!!!

I love it, it's so airy and blessful. Namaste.

Well I don't. It sounds like a 70's game show...

...actually now I think about it, 'Namaste' does too... Albeit an early naughties one, probably on channel 4

It can be something from therapy, yes.

The way they use it, however, just seems like a way of getting out of trouble with others

It will always be an opinion no matter how it's dressed up.

That is the whole point - somebody's truth is only ever an opinion or a perception.(including Bobby's ugly on the inside comment about Farrah)

It's just arrogant to think that your opinion is THE TRUTH.
