As we were finishing Boxing Day dinner, Sarah came into the room with her boyfriend Joe ...
 
Daddy (to Sarah & Joe):  Would you like some food?
Sarah (adolescently dismissive):  No thanks
Maman (maternally dismissive):  They'll feed themselves with cornflakes
Joe (surveying the cereals):  I can't even see any cornflakes!
Evie:  You just don't get the sarcasm, do ya?
