If you were at a coffee shop, and you over hear people talking about somebody, consider it a good sign for that person. For example, at the local Philz coffee shop, and I overheard two guys talking about Elon Musk, and a guy who used to work for Elon Musk at Tesla.
Therefore, we can identify Elon Musk as an interesting person, as he has talked about, even when he is not around.
