He was ill.

Apparently very very ill.
HIs head hurt so much that he couldn't possible go to school.
Luckily around 9.05 the pain started to ease and by 9.06 only his brain hurt. By 9.07 even that pain was starting to ease and by 9.08 he could have won awards for the most well and lively child around.

It has been quite a long day....
