Sometimes happens occasionally in time, rather than all of the time ... it is a very short time.
Never happens at no time in the past, present, or future; not ever ... it is a very long time.
Sometimes ... Never
It may not be now, it may not be soon, it may be in the days yet-to-come time,
But whether it´s soon or a long time from now, there´s a chance that it could happen sometime.
So never say "never" and never say "always" - there´s always at least one exception,
And so if you ever should hear in the hallways a "never," it´s always deception.
