Similarities and Differences between INTP's and INFP's

This year I had a wild experience of rooming in college with a fellow INFP. When I first met her I thought we had crazy similarities, we loved the same music, enjoyed the same classes, shared the same major, both liked photography, and were into writing. However, I soon found that our the way we perceived things was completely different. She based her opinions and made decisions solely on feelings (Strong Feeler) and everything I did was revolved around my thinking analysis of things (Strong Thinker). Although these differences caused a cross in communication and understanding at some points, after some time we came to know and understand how the other functioned and became quite the dynamic duo. We became best friends and did everything together, the only time spent apart was when we had to go to classes. With this being said, we would have the same exact day which would lead to us ultimately thinking about the same things, so much sometimes it was almost creepy. One of us would bring up something on their mind that had occurred and the other would confess to thinking about the same thing.. the only difference was the way we interpreted those thoughts. It's as if we were on parallel train tracks, the only difference being the energy fueling our trains.


..I thought it would be interesting to get some feedback from other INFP's who have been friends with INTP's or vice versa. Input would be lovely!
