For an apology to be meaningful, it must comes from the
heart.
Forcing a person to apologise just because You think you are
right, doesn't make a whole lot of sense.
If that person feels remorseful of his/her own mistake enough to
overcome his own pride and dignity to offer it on his own free
will. Then can you consider it a true apology and deserve your
heart felt acceptance.
Forcing another person to apologise to you.. is just about
your one upmanship. Your ego is the problem.
