The greatest gift that we can often give others is to simply be present and to listen. We don't need to fix, provide solutions, or rush in with all of our own energy. Simply witness, understand, and remain open to whatever is coming up.
When we can truly listen, without judgement or bias, without shutting down or turning away, then we can truly be of benefit. We can hear what they need, and they might feel comfortable enough tell you.
The door is always open.
