I've always found such cases weird. Like, when you plan to have something done, say "by the end of July", and then it's mid way through August and it's still not done, how exactly did the person plan to have it done that early? One thing is for someone to miss a deadline like this by a few days, but half a month.....I'm not complaining or bashing him in any way, nor am I implying he's not doing his best. Just making an observation. Maybe something unexpected happened, who knows.
