关于一位做白日梦的健忘的数学家的轶事。anecdote about the absent minded mathematician.

他到了议会的地方之后把他的车停放在大土地空地上。 开完以后他回大土地来回到空地，不过他忘了是哪一个地方停放了他的车他的车停在哪一个地方。虽然是他自己的车，但他甚至连车的外观都不清楚不记得了。所以他等候剩余的车都没有了到其他所有的车子都开走了之后，把剩下的一部车开走了然后坐最后残余的一辆车。有一天他跟他家人动迁搬迁到其他的离以前的房子不远的一个地方。当那时候，他老婆知道他是一个作白日梦的人健忘的人，所以一旦的在一张纸条上给他写下怎么找到新房子的指示。不过当他晚上离开他办公室的时候，他怎么想也想不到自己把那张纸到底方放在哪了。因为他想不起来他的新房子在哪里,所以他代替只好把车开到以前的房子那里去。他在那里看到一位小孩子，于是就问她："小女孩儿，你知道Wieners新的新家在哪里吗？" 她回答跟他说："爸爸好，当然知道了；妈妈跟我说你好很可能在这儿，所以她差遣我了来让我到这儿指给你看怎么走"。

He went to a conference and parked his car in the big lot. When the conference was over, he went to the lot but forgot where he parked his car. He even forgot was his car looked like. So he waited until all the other cars were driven away, then took the car that was left.
When he and his family moved to a new house a few blocks away, his wife gave him written directions on how to reach it, since she knew he was absent-minded. But when he was leaving his office at the end of the day, he couldn't remember where he put her note, and he couldn't remember where the new house was. So he drove to his old neighborhood instead. He saw a young child and asked her, "Little girl, can you tell me where the Wieners moved?" "Yes, Daddy," came the reply, "Mommy said you'd probably be here, so she sent me to show you the way home".

“做白日梦的” means day dreamer and “差遣” usually means to command. "让我到这来" should be okay for  "sent me here". But I mean after all, really nice work!
