What's cooking

I bought some of those foil blankets (the one's they use in emergencies) with the idea of using them in the greenhouse, draping them over my cuttings and cannas for extra warmth, the grandkids asked if they could open one of course I said yes, they had a mess about with it then left it, about an hour later I came back in the house from outside and what do i see? My wife must have dozed off, so what had the grandkids done? Yep, covered her up in the foil blanket, I couldn't help but laugh, me laughing woke my wife up she pulled the blanket off and she said, I quote "phew I was roasting under there"
