There is a part of a cinese poem(i only can translate it from the words):
when i look at the cloud, i feel close to them,
when i look at you, i feel far away from you.

It might describe the cold relationship in nowadays, people lost trust with each other while feel close to the nature.

Copy one of your phrase: let's keep on trusting people, but with a litte bit carefulness.

Wanner be your friend. And that's what im enjoying going to the lessons.
