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.
The ESFJ Prefers extraversion to introversion. The ESFJ gets energized being around people and prefers to talk out their thoughts instead of internalizing them. They are in tune with the feelings and emotions of their environment and seek to understand it.

Thinking and Feeling
A thinker and a feeler can make for an interesting dynamic. The thinker can help sort through logical issues, but may be seen as harsh to a feeler. The feeler can help the thinker understand their emotions more, but can be seen as too emotional and flighty to a thinker. However, both of these types can make for a very healthy balance.
