On this particular night he woke up and joined us in the living room until the storm was over.
What you can't see is that his hands are firmly clamped over his ears. Nothing--and I mean NOTHING--will get him to remove his hands from his ears until he is 100% certain that there won't be any more thunder.
He won't budge them even when his arms ache because he's been holding them up to his ears for so long.
He won't even budge them when he has to pee really bad and has to resort to crying and begging his mom to put the toilet seat up for him and pull his pajama pants off and then back on again.
