We all agreed to go play tennis on Sunday morning.  At the beginning Logan somehow got himself into a grumpy mood and was being very lazy with his swings.  I lost my patience watching him and told him off that he must have played too much video games.  Logan then perked up and became full of energy.  He asked to play solo, so I took a snack break watching him against Stuart and Connor.  As Logan started making some hits, he became more hyper.  He was running back and forth, and kept the balls going on the court.  The more hyper he was, the better he was hitting, and the more energized he became.  Stuart, Connor and I were amazed watching this unusual Logan, and wondered when he would run out of energy.  However he did not seem to want to stop and had some great rally with Stuart.  I finally demanded to return to court, and Logan and Connor then were done with tennis.  But instead of taking a break, they went out to the basketball court to play 2 squares.  We told Logan how great he was playing, and how cool seeing his energy out there.  He told us that it was his angry energy.  I guess we will have to get him angry more often.
