I whish I could start with “ Once upon a time…” because that would be the easiest way to begin this paragraph (or a paper). Besides, to some extend, “Once upon a time” can be appropriate because this is a story related to the OLD friends of the Paddington Bear. By that, I mean a story about the mega fauna in South America.
