That's why in my school days I never had any issues with someone and whenever I sense that quarrels was coming, I didn't allow it to get beyond control, I will make sure I showed the person that I have let go of the quarrel and I do not have anything in mind to give him hard time.
Up till now, I don't like issues at all, if I find out that a person is troublesome, I will avoid that person, because I do not want to quarrel in any way. What you did was a good lie, so did he later settle the differences with the referee and the other guy?
