I was driving with my kid on Rarotonga and Westfield ave
When this postman with gray dreadlocks was running across the street
While red light was his trying to get to bank on corner
I drove pass and said to him you should wait for the light to
Change his response f*** you and gave me middle finger
In front of my children and me
Very angry postman I know this cant be a shock
To who ever reads this
