Saturation

I once read somewhere that every relationship has an expiry date. Of course some endure, but they just have longer shelf life. Others rot from the inside. Some are kept chemically alive. But aren't relationships beautiful? At least until the expiry date nears. And the end is really horrifying. I fear the death of any relationship as much as I fear the death of knowledge. Yes, knowledge too dies, sometimes.
In a similar way, every place too has a saturation point. After you reach the saturation point at that place, work, home or anywhere, you should not be there. Being there would be like chewing on stale, toughened bread- tasteless, dangerous and dragging.
