I've always felt paranoid about my older brother catching me dressed or finding out somehow that I do. He knocked at my door in the morning a couple of weeks ago because my phone wasn't working. The only female garment I had on were women's slacks that I wear as pajama bottoms once in a while. I didn't bother changing and let him in.
He acted like he didn't notice the mint green pants I was wearing, so I just left them on for about an hour as we talked in the kitchen.
Anyway, maybe this was a way for him to grasp onto my secret without totally shocking him. But I'm sure it won't be brought up in the future, unless he sees me wearing lipstick or something.
