Dori and ephraim are out on their fourth date, and they are really enjoying their time together. they sit next to each other during dinner, occasionally touching hands and whispering into each other's ears. at no point during the meal is there more than one foot of space between them. technically this is a description of space.

Technically this is a description of "intimate" space.

Presently individuals additionally have an intimate space  around them. The intimate space for the vast majority is in the vicinity of 3 and 18 crawls from their body. When you cross into somebody's personal space, contingent upon the circumstance, they will unknowingly take it as a demonstration of physical hostility or as a demonstration of physical closeness or a blend of both. When you cross into somebody's personal space, it's not something that they react to in view of basic thinking soundly.

It's most likely choice a, it makes the most sense in my opinion.
