Absolutely true.

Another angle that goes unmentioned: "the more you know someone, the less you like them."

Most strangers in 30 minutes won't show off their ugly side. It takes a lot longer for those rough edges to come out, and for the really bad parts to surface in human relationships.

For some people, we can look past that. For most others, our interactions would not be so positive.

> "the more you know someone, the less you like them."

That is completely the opposite of my experience. Even the handful of people who, after I got to know them, turned out to be unprincipled or toxic, I actually liked them as people and were kind of sad that they were the way they were. Their negative qualities were a mar on the their individual beauty.

There are certainly people in whom, after a relatively brief interaction, I didn't manage to see anything I liked. But I can't think of a single person whom, after seeing something to like, thereafter didn't see anything to like. Their ugly side may have made me want to avoid interacting with them as a whole, but it never completely eclipsed their good side.

For me, nearly all negative interactions come from not being able to get past various masks to see the interesting part of them or vice versa.
