You get back upstairs, and call Tim. You're not sure how your relationship is as a girl... actually, you should change your girl name. Nate isn't the most feminine name. How about "I wish that female me was called Noelle." A quick shift later, and your driver's license reads 'Noelle'.
Anyways, you aren't 100 percent certain what Noelle's relationship with Tim is, so you call him as Nate.
"Hey bro!" He says.
"Hey Tim, you wanna hang at the mall tomorrow? I gotta pick up some more shampoo for my little sister."
"Of course, but uh... Can we stop by the grocery store afterwards? Gotta pick up some gluten free flour. Estelle's 90th birthday is next week; I'm making her a pie."
"Sure, sure. Am I picking you up?"
"Nah, I'll make my way there."
"Ok, goodbye!"
"Bu bye!"
You put down the phone and decide to find out what Noelle's relationships are like.
"I wish that I had a notebook filled with the different relationships between Nate and Noelle."
A leather-bound notebook appears in front of you, landing on your bed. Leafing through it, your worries are abated. There are pretty much no differences between the two, at least, not positive ones. Instead of someone thinking "That fucking prick" they'd think "That fucking bitch", your little sister thinks "Best big brother" or "Best big sister" etcetera.
You decide to go to bed, getting your pajamas on. You fall asleep in your bed.
