最过我有一次经历，突然被加入到Facebook上一个新的好友群上，自从小学以来，超过20年的时间我们都没见过面。

I've recently had an experience where I was suddenly friended on Facebook by a new group. People I have not "seen" since we were children in elementary school, more than 20 years ago.

自从小时候我就认识玛丽了，我们一起读完小学、中学和大学。

I have known Mary since I was a child and we went to the same junior high school, senior high school and university together.
