A person sits at a table outside drinking beer.
A man is watching his children play outside while having a cup of ale outside.
A person does not imply gender or age, therefore it cannot be assumed that it is a man; likewise, not all beers are ale, that information cannot be inferred.  There is no indication that the man is watching anything at all, much less that he is watching his children play, the presence or actions of any children cannot be assumed.
