missing people who are missing in your life...is that normal?

One of my friend was in a dilemma. She had this question in her mind,
 "is missing people who are missing in are lives quite normal?"
People tried to answer her question, so did I, but somewhere it made me think about it deeply.
How many people were there in my life who were an important part in these 20 years but are not now..!?
I dont know, I really couldn't sit and recall everything, or to put it better everybody.

The next question in my mind was..What should be the intensity of missing someone??
It does depends on the level of importance one has had in our lives, but more than that, it is a fact that plays a vital role and that is how much have we moved on?! Someone said its hard in d beginning and its okay to miss d freshly sliced part of your soul, but later on, crying over something which is long buried is abnormal. But cant we just shed a tear, and miss d person normally, may be even remembering the happy times??.. is that hard??.. the answer every individual has is different. "Depends on the level of importance ....If it is good ridance of garbage then dnt" was the answer for someone but for me, "it depends....emotions sway us away many a times to wrong directions, we shouldn't go for it.........but yes if missing the person who had a major place in your life and sumwhat is the reason for emptiness..dont stop the feeling...feel every bit of it"..its like if we can laugh over the happy times why not at the sad ones..enjoy every bit of your life and face it as it comes.

If its, the gifts and souvenirs that we are ready to keep aside, away locked in a box, its 'cos we never want to have an encounter with it. We simply are running away, but we forget that its just an action which doesn't hold much of importance. Somewhere somehow you can be reminded of the past, probablity being 1, and the souvenirs will have no role to play at all. Then whats the use of doing it when just the flash of the name pushes us back in the past??. People think that, if it has got to do with relation then the future life partner might have a problem. But isn't that a shield we are using, rather corvette to protect  ourselves from the attack of other's who still believe that at the end of the day "WE ARE BOTHERED". We are ready to move on and experience new memories instore but new one's can never take the place of the old one's. Every one has a distinct place in our life. May be their value decreases with time.
We are great liers, but the reality never changes. It remains rock solid...
and yes its normal..
