Road Rage?

I was returning from picking up our remaining Color Me Rad race kits from Down Town.  4 people had not picked theirs up.  One I knew for sure, but if the other 3 aren't running, our team will only be 25.  Anyways I was going southbound on Donald in the left hand turn lane to Osborne coming to a red light.  A lady in a convertible was pulling out of a parking lot, so I let her in and she took the next lane over.  The light was still red, so I let another lady in a mini van exit into my lane.  I immediately heard honking behind me.  At first I paid no attention to it.  Then the honking continued as the light turned green.  I slowly advanced and looked in my rear view.  Some older man was signalling 1, 2, 3 with his fingers, pumping his hand on each count and mouthing out the numbers.  I found this odd.  He did it a few times.  Was he counting the cars I let in?  No, it was only two.  The seconds it took for them to enter traffic?  Not really sure.  I shrugged at him.  He continued to count to 3 on his fingers and I shrugged again.  I turned left and came to another red light.  This man pulled up behind and again blatantly counted to 3 on his fingers.  What's with this guy?  I was just being considerate of others.  Really, neither car affected him.  The first lady took a different lane and when we turned the second lady took the 1st lane and this old guy and I took the 2nd lane.  We all made the light and with traffic in front of us, would not have advanced through the intersection.  So I closed my fists and made like I was rubbing my eyes to signal that he's crying.  He then laughed and clapped at me.  What has our society come to when letting 2 people into traffic upsets someone to the point that he's honking and trying to indicate that I let too many people in.  Really, I don't see the big deal.  Well this man pulled into the first lane behind traffic while I advanced and pulled into the same lane several cars ahead.  I never did see him the rest of my route home. As long as people signal and aren't trying to blatantly cut the line, I have no problem letting people into my lane.  Obviously with these two ladies exiting a parking lot, neither of them violated these "rules" that I tend to follow.  So to my fellow drivers, be courteous to each other and we'll have that many less angry people on the road.
