What is not a matter of tastes, but an idiotic design choice is that:
- we are in room A and we click on a door thus accessing room B
- in room B we click on a bacward pointing arrow and we do NOT go back to room A, because hey the camera is pointing in the opposite direction now, so the door from wich we came is the one in front of us...
It's all trade-offs, and there isn't a single best answer.
That's not the definition of second cousins. My second cousin is the child of my parent's first cousin (or the grandchild of my grandparent's sibling, or the great-grandchild of my great-grandparent).
What you're describing are first cousins once-removed.
The general rule for determining what sort of cousin two people are is to compare their ancestors to find the closest ancestor of either of them who's also an ancestor of the other. The number of generations in between that ancestor and the closer of the two decendants is the degree of cousinship (for example, between grandparent and grandchild there's one generation, so they'd be first cousins). Then the number of additional generations between the other descendant and that common ancestor is the number of removals (continuing the example, if the other descendant was a great-great-grandchild, that would be two additional generations beyond grandchild, so they'd be first cousins twice-removed)
