Actually, it is completely random. In one of my families I had the tax man give, take, give, take, and then give in five consecutive emails. In another it seems like all the tax man does is take, and in another he is always giving.
I know it can be frustrating when something bad happens

(especially in the beginning) but hang in there. It won't be long til you have more money than you know what to do with

. (It might seem like forever, though

)
