Blowing away the cobwebs

Went to bed at 2:30 leaving Matthew on his own. He'd mentioned seasoning his cast iron skillet which involves oiling and then baking it for an hour at 175 centigrade. I advised against it suggesting that he was likely to fall asleep. I'm woken from my slumbers about 90 minutes later by alexa. Nipping downstairs, that's a distinct smell of hot oil and one sleepy son making his way to the kitchen pretending not to have just woken up. I resisted saying 'told you so' and just turned around and returned to bed.
