那是一个周四的下午。我发现厨房里的一把大剪刀少了半边。

It was a Thursday afternoon and I found one half of a great pair of kitchen scissors was missing.

也许是累吧，不禁想起看过的一幅漫画，漫画中的人，左手拿着一把大剪刀，正在剪着自己的右手。

May be tired, it, can not help but remember seen a cartoon, cartoon people, left hand holding a large pair of scissors are scissors with his right hand.
