Today my sister and I were hanging in the living room with one of my sisters friends (and my other sister). We started joking about the fact that my sister has this obsession with drawing boobs on the chalk board in my room, and my sister suddenly said "I draw them there because I wish you were attracted to them..." as soon as she said it her eyes got big and she started tripping over her words trying to rephrase that. Could it be possible that she knows...? I'm just not sure what to think...
it definitely sounds like she knows. but it also sounds like she's cool with it. she just let it slip out in front of other people and tried to save herself. you could bring it up with her in private. i feel like it will go well
