Go around!

We're not making a 'point' - we're stating a fact: There's a big difference.

It is better to wait to hear the real reason from the flight deck

You appear to suggest that a PA from CC will not provide the 'real' reason? In fact, with the exception of sudden events such as a go-around, pilots and CC tend to communicate carefully beforehand, to ensure that there is no discrepancy between what each party will say.

it will be quite obvious to me what has happened

Quite possibly, although you will have no understanding at all of the reasons why, or the actions required to resolve the situation. However, this rather misses the point - PA's in a go-around are not made for the benefit of people such as yourself, but for those to whom the experience is potentially distressing. Since it would be absurd to suggest that each passenger be canvassed to assess individual experience and state of mind before being given a tailored explanation, a general PA will be made to all on-board.

Nicholas49 - a little knowledge can be a dangerous thing. Sometimes it is wise to recognise that.
