Connection might be defined as being "held in mind."

My baby's a mystery to me.

This thread talks about how it might start for a person.

I think you and i ARE connecting. In many ways i am quite isolated, but i find IRL interactions to be pretty painful, even with friends i have known for decades. So online has been great for me.

I distracted myself there. But im not lonely because i know these IRL friends hold me in mind?
