When Mike turned seven, back in the 60s, he was rude with his new puppet to his party guests. Likewise with Emily when she turned six. (Listen in for the shocking details.) But what if they had rehearsed party protocol with their parents first? It has become a thing. Plus, we consider "staging" near an elder parent before the needs becomes critical.
The cover art, Rowlf and Mike, is a transfer from Super8 home movies...a Kodak moment for sure.
Emily mentions an article from The Atlantic.com, "The Strange Origins of American Birthday Celerations." A fun read!
