it's pretty rare to have the size of an objet in memory be proportional to the number of times one of its method is called. It's usually proportional to the amount of "data" it stores. In the case of recursion, the "time" of computation may have a direct consequence, in itself, on the occupied memory (in the case of non-tail optimized calls)
