Dad Half Hour
When a dad says half an hour but it's really just time for him to do something else and pretend he was gone.
Dad: 'I’ll be back in half an hour.' (He’s actually at the store buying chips and a soda.)
Dad: 'I’ll be back in half an hour.' (He comes back 20 minutes later and says, 'I had to go to the bathroom.' )
Dad: 'I’ll be back in half an hour.' (He's still there when the baby starts crying.)
