Mate, the trouble with mail is the lack of expression.
I may have even lost a sister over it.
5 or 6 years ago after suggesting to one of my sisters that email lacked something, a "misunderstanding" means I haven't been able to speak to her since.
I probably should be more circumspect in what I say, but bravado or laziness etc, allows me too much latitude.
Ignore my rantings and rest assured I read your opinions with respect.
