My wife related the following story to me about our five year old son:
Every morning as he gets on the bus to go to cheder, she gives him the following blessing: "Bye, you should be matzliach (successful)!"
She told me that a few days ago, as he got onto the bus, the non-Jewish bus driver said to him, "Good morning 'Youshouldbematzliach'!"
Apparantly he thought that was our son's name.
When I heard the story I made a little tefillah that IY"H his name should always be a blessing!
