UrRong, your suggestion of changing direction to avoid the awkward situation does have merit. However, you neglect to take into account one important factor that was included in Nikhil's initial essay: the shame of capitulating or the indignity of overtaking the other person. Depending on the layout of the city streets, crossing the street may not be feasible and navigating a new route may not be possible. Furthermore, changing direction may lead to even more awkwardness if the man and the stranger come across each other in close proximity yet again.
The solution that Nikhil proposed was much more practical and based on two scenarios that are very likely to occur: slowing down or speeding up. By utilizing one of these two options, the man can avoid both the shame of capitulating and the indignity of overtaking the other person. And although neither solution results in a perfect outcome, Nikhil's logic is still sound and should be considered.
Besides, when it comes to avoiding awkwardness with strangers, a little humor can go a long way. With a witty joke or a lighthearted comment, the man can potentially turn the situation into something more enjoyable, making it easier to cope with either slowing down or speeding up. After all, laughter is the best medicine...and sometimes it can also help you avoid an awkward encounter with strangers too!
