I'll be in the kitchen with your mom.
If you're trying to escape a conversation, say this like you're fleeing from a monster and your mom is the monster's best friend.
'I'll be in the kitchen with your mom.' *runs to the kitchen like it's a lifeline* 'I hope she doesn't ask about my hair.'
'I'll be in the kitchen with your mom.' *slams the door* 'I'm not coming back until you both apologize.'
'I'll be in the kitchen with your mom.' *walks away with a dramatic sigh* 'This is the worst day of my life.'
