You're question is about how best to model a domain of which you've given the scantest of details. Domain modelling is something you have to do in any programming paradigm and is equally as obtuse if you don't have proper knowledge of the domain.
Come back with a more detailed description of the domain and then we can start comparing the emergant designs from OO and other paradigms.
The point is, if several objects are involved, all of them get mutated and all of them are in a type hierarchy, you're going to have a hard time justifying which object should be the receiver of the message based on what feels more natural.
