when I grow up I shall be a mechanic librarian priest.

According to Mb, who has just turned nine years old, this is what he will be when he is an adult. 

Not able to settle on one single career, he has gone for a whole host of them.  He loves reading and he loves tinkering.  Which explains the first two, but the third?  I'm not sure where that has come from.

I asked him if he knew much about becoming a priest, and what it meant and he replied "Yes, you get to tell people about God, and you don't have to marry anyone."

I think that he is quite possibly searching for a career that doesn't involve finding a significant other.

Now we've been to the Fun Day, he is seriously considering a career as a bubble blower.
