A guy that is understanding is a guy who listens. Wouldn’t it be great if every guy listened AND retained the information you told him? Well, there are a few who do, and that definitely sets them apart from the rest. You want a guy to understand what you’re going through or the opinions you have, even if they don’t necessarily agree with them. Understanding is such an essential personality trait because it lets you know that communication between you two will go more smoothly than someone who refuses to see your point of view.
