Do you see yourself using email in the not-too-distant future? The path of an email message starts with the sender and concludes with the receiver of the message. Take careful notes on everything you discover. Is there a rationale to the differences, and if so, what are they? Consider the possibility that there exist several models, each of which has a unique level of complexity (or abstraction).

How can I discover an object-oriented approach that works for me, one that prioritises modelling over process, and what are the advantages of doing so? How can I find an approach that works for me that prioritises modelling over procedure? Please provide an example that illustrates one of the arguments.
Imagine email in your own words. If I send a message through email, how does it go from my computer to theirs? Make a tally of everything you've unearthed. Which ways do they vary, and which reasons led to the formation of those differences? Pretend that there is a wide range in the complexity of the models (or abstraction).
