Extraversion and Introversion
An extravert and introvert may have some issues with one wanting the other to open up more, and one wanting the other wanting the other to give them some time alone. However, they can also be good to balance each other out, allowing the extravert to feel more comfortable introspecting, and the introvert has someone to encourage them to socialize and try new things more often.
