Nice to see you! I am glad you agree, and I like what you say about being “guarded” and in your character.

I do feel there is a line to keep where you still know that you have a professional relationship with your customers
while developing a deeper interaction or possibly friendship that will continue, but it is possible to keep this quiet line.

I never got that one too: how can being “guarded” ever establish an honest relationship with prospects/clients? If it is not natural in your character to be “guarded” then when you try to follow this “advice” your whole body-languages shows you’re not happy but your prospect/client doesn’t have a clue why you are not happy.
It is just so counter-productive IMHO. It’s always better to be yourself, in any situation but really important when building a relationship.
