I checked serendipity in 有道词典，it explains that "serendipity" was coined by Horace Walpole in an 1854 letter, from a tale of three princes who were always making discoveries, by accidence, of things they were not in search of. Maybe, you can talk about who is Horace Walpole and what he/she has written about? I like the way 你委婉的讲述一个事情。I still remember your episode about a pop singer named as K Lamar。

also, synergy is a high level word, but I know sync and synthetic.
