I blog, I call it my healthy mental bowel movement. It's quite an offensive thing.
It's also practice for creative writing etc.
But I try and leave everyday events out of it, such as names etc.
As for the original blog,
That doesn't sound like any Sergeant I've met, with regards to his behaivour on a BMQ..especially the "boring" comment.
I mean..those lectures aren't particularly exciting, but you're not supposed to say it out loud..infront of the recruits.
I don't think there's anything in the blog indicative of the recruits quality, I just don't see that so before we lose it on the lad let's pause.
And I didn't think it was a rant at all.
In fact, it pretty much sounds like...average recruit thinking and I think this could be an interesting experiment where we can see the natural mental progression of a recruit during training.
That being said, I think the first reply was bang on when he said no names, specifics etc.
But detailing the events, and your take on said events, is fine just as long as you leave out names etc.
