You add Feelings in your heart and you flush them with time. Time dilutes feelings day by day, and for a long time, your heart don't seem to feel them anymore.
But the feeling remains. One day, something triggers that emotion back. It's drains all the time away. The sudden awareness of these feelings makes you feel that they are back, stronger.
But feelings always stay the same. It's the sudden drain of time that makes you feel that way.
A feeling never goes away. It will never go away; it can only be diluted. The feeling only 'comes back' when you will time to stop.
