I once read that one of the most important things you can do in a relationship is to come right away when your SO calls for you. The alternative is to ask what your SO needs, and then decide whether or not it's worth it for you to go.
When you call for your SO, do they come right away (or as soon as they can)? Or do they ask you what you need? Or haha, do they just not hear you.
What about vice versa?
