"avec moi..."

Indeed.
The greatest thing is...I could sit with you, and no say anything.

...And when we leave, it would of been the greatest conversation ever...
I mean after all true friendship comes when silence between two people is comfortable.
...never saying a word, and walk away feeling like that was the best conversation you've had.

Silences make the real conversations between friends. Not the saying but the never needing to say is what counts...

If a friend is in trouble, don't annoy him by asking if there is anything you can do. Think up something appropriate and do it.
