I don't know what was said or what wasn't said. I know this thou, your job doesn't make you better or worse. People have different skills and so long as you can be productive in life, then who cares what your job is? That's how I see it.
I am fortunate to have had a life where I've done OK, relatively speaking of course. But I didn't start out that way. My family did not have money or anything even close. We were poor but, our parents and our Uncles and Aunts sacrificed for us so that we would have a better chance. I am grateful for that. Heck, I've had a few Uncles who had full time jobs during the day and sometimes worked as Security Guards at night, especially around Xmas etc. It is what it is. Doesn't mean the Guard is a great guy or whatever, just means that being a Guard does not make him such, out of hand.
