I know how that conversation went this morning 
2 boys, 1 mum. 1 boy in trousers and very wrapped up. 1 mum very wrapped up. 1 boy in shorts and a light coat.
I just bet there was a
"put your trousers on"
"I don't need them"
"you'll feeze"
"no I won't"
"do what you like but you will be cold all day"
Or I am projecting and that only happens in my house?
