Thank you so much for your help, TheParser. I'm interested to read your formulation of 'warmer' and 'colder', which makes me understand the sentence better.
Thank you again.

(1) Thank you for your kind note.
(2) By "cold," I meant
distant, formal, etc.
(3) By "warm," I meant
emotional, intimate.
(4) How are you? Great seeing you. What have you been up to recently? = "warm."
(5) Hello. It is nice to see you. Do you wish to share with me any news about your recent activities? = "cold" or, at least, "cool."

I read two sentences similar to these:
I like to camp. = A formal statement of what I like.
I like camping. = More emotionally involved (I can even smell the trees and hear the
birds singing).
