Whenever I meet another whistle walker on the street one of two things will happen. 1. The other walker wasn't whistling, and they start. or 2. The other whistler was whistling already and keeps whistling. You can assume that I was whistling for the sake of this post because I would never start whisting if someone else was already whistling.
In either case a number of options are available now that you are both whistling.
Whistle Options:
a. You can stop whisting - This doesn't seem fair, because you were walking along minding your own business, and it is your right to whistle wherever and whenever you want to - Except in the work place (
Peril of Workplace Whistling).
b. Whistle along with Whistler B. - You will get all different reactions, but in my experience this is rarely a good choice. You may get attention that is unwanted since you are essentially puckering up.
c. Whistle your own tune louder - This is an act of escalation which may not be within your aggression range.
d. Consider a walking option.
Walking Options:
a. Stop walking - this can be effective if the other person is walking. A natural separation should ensue.
b. Walk slower or faster to remove yourself from the situation.
c. Walk in the opposite direction. Caution - this could take you out of your way.
I hope you find this post helpful next time you are in one of these awkward situations. Your best bet will be to think on your feet, try to keep as many options open as you can, and keep your stick on the ice.
