I don’t think it ever becomes normal to miss the ones we love. Most people are forced to think of seperation as a circumstance or situation, something they have to wait out or overcome.
Time is so cruel. Especially when it steals our weak, takes our elderly, and our precious young before we are ready to let go, we don’t give proper attention to what time gave to them. Possibly it was all the time they needed. Something unperceivable was going to happen that time was being the friend and let them stay innocent to such pain or anguish. We are much too selfish to let time off that easily, so I digress.
