I don't know, maybe I misunderstood Jim's post, but I interpreted what he was saying as, because WE appreciate and require space to sift through things, our natural response might be to assume the other person would need it in the same way. Of course, knowing about mbti stuff and how everyone's different, you might learn not to do this and you will learn the other person might not want/need the space, but we might initially, gut-reaction, give them the 'gift' of space because that's what we like to have. (You know, that whole projection concept.. having a hard time stepping out of our own selves and realizing that, hey, other people don't operate the way we do! Wow, what a concept! haha.)
So, if I'm 'giving space' to someone I like, and am in a relationship with them or something, it's as simple as, after hanging out or having a discussion, I'll let them have down time for a day or so and won't bother them. But, if they'd immediately want to chat or whatever, or discuss, or would want to meet up the next day, I'd be quite all right with that.
I sort of put the ball in their court - or, at least, that's what I see it as, although they might see it differently of course.
Giving the gift of space to someone I LIKE means I'm already involved with them and they have an active part in my life - that's clear.
If I didn't like someone or was avoiding someone, they wouldn't really be in my life to begin with.
