i was gonna say... - When someone interrupts you mid-sentence and you want to scr

When someone interrupts you mid-sentence and you want to scream but you just say this instead.

'I was gonna say... you're so loud, I think you're trying to wake the dead.'

'I was gonna say... your interrupting me like I'm your personal doormat.'

'I was gonna say... you're the reason I've started talking to my cat more than you.'
