Ystwyth,
What these gents are trying to say is that a go-around is a normal part of flying and is more likely a sign of good judgement than poor performance. Just another day at the office.
Plus, it's unlikely anyone here would have any idea why a specific flight went around. There's no "Ivory Tower" here...just a bunch of professional aviators, most likely.
P.S. It's OK to ask questions...
