When saying complete means the opposite

I usually hear or read the words "I am complete" but do they really mean it? I find myself wondering if the person saying this is true to him or herself. I do hope that what she does mean what she says. and if she does mean it then I'm happy for her.

I find myself wondering why do I feel pity those people who says I'm complete when their actions speaks otherwise. When a person is complete, he or she does not need to tell the whole world repeatedly about how he or she feels. and besides, A complete person never talks about his or her past sorrows. It seems more like a person who could not go on with his or her life.

If you are complete, all that is past is left behind.
