Well hypothetically each mouse button has a certain finite number of clicks in it before it breaks.

It could be in the future you'd need to click to send some crucial evidence to stop you getting sentenced to death. It could be that this saved click is the difference between the mouse failing or not on that occasion.

Of course the parent clicked send on their comment undoing the OPs good work.

This is all astoundingly improbable, but people buy lottery tickets each week.
