The social calendar of a 3rd grade boy

So I have recently found out that, without my knowing it, 3rd grade has now become the epicenter of the universe and I "just don't understand." 

Today was the first day back to school after a long weekend and my son was scheduled to have a play date.  Now when I was a kid, a "playdate" meant riding my bike down the street on any given day and knocking on a friend's door. 

Well, this is not the way of the world anymore!  Now, we have bus passes and advanced planning must be made so he knows exaclty which mini-skateboard to bring.  He can't bring the blue one to this friend's house because he may already own it AND he wants to have a playdate with a DIFFERENT friend next week, but that friend DOESN'T have the blue one so he might want to bring it then. 

And apparently the playground is no longer just for kickball at recess- it is now the headquarters for official business related to all things 3rd grade.  You have to know the "secret password" to enter the wooden house at the back of the monkey bars...and of course, no girls allowed.  But the girls can still chase you around the playground if you're foolish enough to stray from the house...except now you have bodyguards to make sure they never catch you. 

So, you ask, what goes on inside this secret, wooden house only meant for 3rd grade boys?  Well, it's the home of the Cool Kids Play With Legos Club, of course.  But it's by invitation only- you must receive a secret note inside your desk before lunch time to qualify for entry into this elite club.  And, I'm told you must bring your best Star Wars Lego ship to school as well.  Of course, I only know this because I have the audacity to say "no Legos in school or else they will get lost" and I'm met with a crying, red-faced child telling me that he won't be cool anymore.  Oh the drama.  He's right- I "just don't understand!"
