Leaving/Janet/Ask what gave it away in advance
From Create Your Own Story
"How did you know?" you ask your sister.
She smiles. "Certain small clues gave it away. You were behaving more feminine, keeping yourself clean-shaven, not hanging out with macho males from school, things like that."
"That could apply to lots of quiet types."
Your mom chimes in. "I had a suspicion, too. We women know one of our own kind."
Your dad just sighs. He clearly feels like he's the only one out of the loop.
"Don't worry, dear," your mom teases him. "Women are smarter than men, but I love you anyway." She kisses him on the cheek.
"How about those makeup tips now, sis?" your sister asks.
"Maybe I should give them to you," your mom suggests. "I have many years of experience."
