It is these skills that enable us to develop lifelong friendships. When we see the phrase ‘as we know’, we can clearly know that the writer is trying to refer to common knowledge.

Have you found out how she uses that method? 【鼠标】Well, it is in her blog, line 12 – 14, nowadays, your friends are just a click away.
