The term "Monday morning quarterback" was coined to describe the person
who watches a football game on Sunday without participating, but then has
all kinds of criticism and advice to offer the next day. It is easy to
judge the way someone handles something if you aren't knee deep in it
yourself. There are some things you just can't understand if you don't
experience them. You may feel you have a good idea of what someone in your
life should have done in a particular situation, but you may not know the
whole story, dear Moonchild. Hold back from assuming that you do. Just be
supportive until you learn more.
“星期一早上的四分卫”这个词是描述一个人在星期日看足球赛，可是他没有实际下
场踢球，不过他在隔天却有各式各样的批评跟建议。如果你没有亲身经历，那就很容
易评判一个人处理事情的方式。如果你没有经历过某些事，那就很难真正理解。对于
你生命中的某个人该如何处理某个特殊的情况，你也许会觉得自己有很好的想法，但
是你可能不知道来龙去脉是怎么样，亲爱的月之子。先不要做你默认自己该做的事，
在你知道更多之前，先表态支持就好。
