I don't disagree with you.No different from celebrating the anniversary of when you got together.
In response to the posit Serious question. Marriage shows nothing to me. It would show great commitment if divorce was impossible or even difficult to obtain, but it isn't., I was merely pointing out that like any type of anniversary, your wedding anniversary shows commitment when it reaches those lengthy milestones; conversely, like any type of anniversary, it won't show commitment if you break it early on.
I hope that makes sense.
