an extra loud reminder that SJ has PDD

The boys had a sleepover at Isaac's house last night.  They are still not fully recovered from our vacation, so they have both been staying in a tired, crabby state for days.  When I picked them up today, SJ was especially whiny.  He wanted to go to the pool, but I had other plans.  We were going to stop for lunch and I had a few things to take care of in my house.  The neighbor boy came down to play with Bob and SJ.  I was fine with this since I was going to do some chores.  A few minutes after the boy arrived, SJ declared that we were going to the pool.  I told him again that we weren't and all Autism broke loose.  He started crying, yelling and rolling around on the floor having a full blown toddler's tantrum.  I gave him a warning to settle down, but he was not able to begin to comprehend what I was asking of him.  The tantrum continued for a few more minutes, so I put him in his room.  It didn't really help him calm down, but at least it was a small buffer for the boy, Bob and I.  He would appear to calm down after a few minutes and I would let him come out.  Then, the tantrum would reescalate.  I would again put him in his room to calm down.  As soon as he was out, he would start again.  This cycle went on for about 60 minutes.  I just wanted to pull off my head and throw it in the weeds.  SJ's PDD on most days in fairly invisible, so I almost forget that he has PDD.  Today, I was reminded very loudly!  Fortunately for our family, these days are seldom unlike some other families that suffer with these symptoms daily!
