J: Hey Zach I'm just taking Leo out for a walk, could you turn the oven off in 15 minutes please.
Zach: Ok - 15 minutes, turn oven off. That'll be half past six. I'll set a timer for 15 minutes on my computer
J: Thanks honey
15 minutes later.
Text from Zach : what was it I was supposed to do when the timer went off?
