@avrammd again Im being misunderstood. I wrote that the Rebbe is human in the very line you quoted. 5ish rephrased it nicely. As for how we talk to our Rebbe, see this mainstream Chabad camp song below:
Rebbe mein teyere Tatte
This Pan I write to you
My emotions deep within me
I can only turn to you
I hear them speak of farbrengens
Of hours spent together
Of your hand constantly giving
And a smile of love and care
But Rebbe I’m so young
I feel so very small
I wish I too had a memory to recall
How will I grow to be
What the Rebbe wants of me
Tatte please tell me how my life I should lead
My kind, dont worry I’m here with you
Learning my Torah makes it clear to you
That the world is ready the time is near
Spreading my Torah brings Moshiach here
Higiah zman Geulaschem
Repeat: But Rebbe I’m so young…
