We can cry, mostly in situation in which a tragedy is involved. Or, we are so deeply in love or have a big feeling under this situations. And yes, people can express feeling in their own unique form. But crying is not only a way to express your inner mode, but also is a unique way of releasing energy and let ourself go into a new state of peace with our hearts.
Some men show affection differently than others. For some, it's hand holding or wrapping their arms around you for no reason other than they want to. For others, the best way they show affection is to change the oil in your car or fill up your gas tank without you asking. It all depends on the man.
One thing is for sure, though. We need to make sure they know we appreciate all those little things and we do little things for them as well.
I agree, it is interesting learning the different ways, and yes it is important that to show him appreciate. I think in some cases, it's best to be with someone who show affection in the way we prefer also. In this way, no one will be disappointed.
