Why is it the wedding ring is to put at the fourth finger?

Just want to share something here which i find it quite interesting.

Thumb represents PARENTS

Second finger represents SIBLINGS

Centre finger represents OWN SELF

Fourth finger represents YOUR PARTNER

Last finger represents YOUR CHILDREN

Instruction: Try to follow the picture below shown. You will find that only the fourth finger cannot spilt opened.

Try to open your thumb which represents parents; our parents will have to leave us one day because humans have to go through the life cycle.
Please close up your thumb.

Try to open your second finger which represents siblings; they will have their own family to take care and eventually will have to leave us.

Please close up your second finger. Try to open your little finger which represents children; sooner or later, the have to leave us as they have their goals to go for.

Please close up your little finger. Try to open your fourth finger which we put our wedding ring; you will find that it cannot be opened at all because it represents husband and wife, the whole life you will be attached to each other.

Real love will stick together, forever.

"People always mention that relationships are complicated. To me, relationship is never complicated if no one has changed; it will be... when one has changed. When the relationship flows smoothly, love has exist where real love will exist pretty soon; when each and another holds it tied, the love will stay for long."
