• who wakes the other one up with kisses

Definitely Jules. 

• who cooks for who

Unless we want them to burn to death in a fire, or die from food poisoning, Sam cooks for Jules.

• who is the morning person/night person

Jules is definitely the night person, and Sam’s the morning person.

• who is the romantic one

They’re both romantic, though I think Sam is more of a romantic than Jules. 

• who is the top when it comes to sex

Jules is definitely the top, though she often teases Sam about being the bottom, and wants to try being bottom every so often.

• who would lead in ballroom dancing

Sam. No questions asked.

• who is the more cuddly one

Sam, though depending on her mood Jules could give her a run for her money.

• who is the one to most likely pick the movie they watch

They share this privilege. Though Jules will often try to convince Sam not to pick a horror movie.

• who is the one who would pay for dates

Jules insists on paying for everything.

• who is the one who would initiate a quicky during classes

Most of the time I see Jules being the one to initiate things, though on occassion Sam would definitely start things.
