An example of this is when two friends want to talk alone, just the two of them. They want to open an intimate topic, something that really weighs on their hearts... but then a third person walks in and begins making small talk. “Hi, how are you... You can continue talking—don’t let me bother you.” Sure, they can continue talking—about the weather! They try hinting that they want some privacy, but he doesn’t get the message, and they’ll have to pick up the conversation another time.
When a Yid finds himself in a challenging situation, and ten people would be there along with him, struggling with the same set of challenges, he may be able to speak about the matter with this one or that one—but he wouldn’t be able to speak with the Ribbono shel Olam in an intimate way. His pain wouldn’t bring him deveikus in Hashem.
For this reason, the Ribbono shel Olam has designed it so that we will often suffer in solitude, simply so we will feel, “I cannot even discuss this problem with my closest friends and associates... they’ll never understand me... I’ll stick with the Ribbono shel Olam.” Ah, you have no one. You’re alone. Now’s the time to open that Tehillim. Speak to the Ribbono shel Olam in your own words. Sing. Say Shir HaShirim... like there’s no one else here!
