The old resists the new one.'Change hurts' is the reason.

People tend to resist a change into something new and different.But after it's succeded, they easily say that the change is a must.

O: Hey youngman, you should respect me!Y: Hey oldman, you should understand me!

When you're young, you say what you feel.When you're adult, you speak what you think.When you grow old, you listen to what nature says.

You see yourself as if old and wise.I see you really miss your childhood.
