Know your ISP. Ok, so my kid is in grade 2 and today when my wife went to pick him up from school, one of his class mate's dad walked up to the car and started threatening my boy saying that stay away from my child and that he can be very nasty. My wife was trying to reason with him but he just kept going on and on. He said all those things and then went away. My wife then started talking to my son to find out what is going on. He then turned his car and again came to my wife's car and again went on along similar lines. What she could gather from this was that my son did something naughty to his boy. The father of that boy also said that he did not want his son to be in son's class and my son is very naughty. So after this tirade, my wife was bit shook up and she called me. I was at work at that time and asked her to give the boy's number. I called his dad and when I mentioned that you were threatening my wife and kid, he said he did not do it and that my wife must be lying. My son's been going to same school for three years and not once have we had a complain against him. The other boys father was trying to portray my boy as the bad apple of his class. The
