Dad Went To Get Milk
If your dad says he's going to get milk, you can bet your last pair of socks that he's with a new woman, and he's not coming back.
Dad: 'I'm getting milk.' (He was at the mall with his new girlfriend.)
Dad: 'I'm getting milk.' (He came back with a pizza and a new phone.)
Dad: 'I'm getting milk.' (He's now living with his ex.)
