The answer is C. "the man's behavour led me to guess...upset in someone."
Sentences A and B describe the actions and manners, showing the man's behaviour and anxiety: casting quick glances, his foot beating on the hot pavement etc. appearing he could even explode with anger. At some point (C), <em>he changed and just got calm, wainting silently, leading the speaker to wonder if the cause of all this could be the bus' delay.</em>
It would be C because reflective writing is where the writer describes a real or imaginary scene or event and adds a personal reflection on its meaning.
Well dear,
Think about it, if you stopped putting things off you would get everything done right?
And when you do procrastinate and have a lot to do how do you feel?
Stressed maybe? Overwhelmed?
How would you feel if everything was done?
