Me and HR had this tendency to ask the other person questions we know the answer too. Rhetorical you might say. But, that's is just how we roll.
"Sapa yang tak gantung kunci kereta ni?"
"Who left the lights on?"
"Who forgot to throw the rubbish again?"
"Whose cekak is this?"
We know it is just us two in the house. If it is not me than him. But we like to ask and annoy the other person anyway.
Can I wish that I have a baby so that I can say, "It's the baby!"
