When a partner asks you to do something that you truly don’t have time to do, it is important to learn how to say “no” to maintain some sense of work-life balance. You will learn that, the more detail you give as to why you can’t do something, the more likely it is that you will convince yourself you can fit it in and end up doing it. It is therefore best to be vague and use phrases such as, “I am totally jammed up”, “I am wildly jacked in”, “very tied up", "getting crushed", "totally slammed", "getting killed", "completely swamped." This leaves some mystery as to why you don’t have time for a new task. If the partner asks me to explain in more detail, I like to just say that I’m more of a “big picture” guy and then crabwalk out of the room.
