From one perspective, you are the deciding factor, the crucial element. You and only you decide how you are going to walk a Camino. Body language says everything. I can see someone walking and, without knowing anything about them, can immediately tell that this person is in a zone within itself and does not want even a soft and gracious 'Good Morning' greeting. He/she gives all waves of vibes that say, "I am in my zone of no contact." And to those who are ignorant and oblivious of this person's state, as they blindly issue a 'Good Morning!' greeting to this person, he/she does not respond; it is as if no one outside his zone/world exists.
I babble on this to make the point that your Camino experience is made by you and you alone, not by those around you and you are the one who chooses the level and frequency of contact. For example, on a Monday you and only you decide this will be a day of social interaction and reaching out to anyone and everyone. On Friday, you and only you are 'allergic' to humans and remain within your shell regardless of what is going on outside you. Either or both are fine. Just decide how you and only you want this to play out.
I am not sure an of what I just said makes sense, but thank you for giving me the opportunity even if I blew it.
All the best.
