Memories

I read that when one start to keep recapping fonder memories, it might be because there is something in the present that you cannot handle, such that you keep searching for better times to comfort yourself. Maybe it is just the tendency that everyone will want to be happy, but apparently when you are stress or troubled you will tend to seek comfort in past happy memories, though somehow i feel that won't that make you more unhappy, because you just miss the good old times.
