Don't worry mate. I was being trite. Jack Tatty recently started a post by asking someone "are you mental"? Physician heal thyself , it would seem.
Although @Jack Tatty (Formerly LouisBalfour) and I had a bit of a virtual toe-to-toe last week (perhaps you saw it), I'll defend him here. You shouldn't mock someone for their mental health issues, particularly when that person has come forward and been brave enough to speak about it. The use of the word 'mental' may have been poorly executed (I didn't see it so can't comment), but that doesn't take away from his own battles, which have been well-documented. Let's not play them down, it's disrespectful and wrong to do so.
Of course it is. I would not do that unless it is to discourage the sufferer not to do the same to others.
