Why Doesn't Time Stop?

There have been several times in my life I wished time would stop. I recently went to the funeral of a dear woman, her daughter and I were talking about losing our mothers and why time doesn't stop just for a moment. Why are people still going...can't they just all stop for just a moment and let me catch my breath? I have had big events in my life that have made me feel this way. I have also had small insignificant events as well, like being with a good friend for lunch and not wanting to leave b/c the conversation is just that good, looking at my nieces or nephews and wanting time to stop because the moment is perfect with them in it. Time needs to stop for a long overdue hug as to pay homage to that exchange of energy. The ramblings of my mind are endless but useful to me...
