The Box No-one Else Understands

Here is a box that is special to me,
Hidden secrets triggered by memory.
The box is plain, just pink with swirls
But the inside treasures kept like pearls.
Open the lid and see inside
Material objects, nothing to hide.
But if at the time, you and I stand
Only then will you understand.
These objects are common, just a simple thing,
Not valuable in price, but values in meaning.
Within the box lies souvenirs,
From my family, and my peers.
This sacred chest, where my treasures belong
Will hold a special place in me, no matter how long.
Because this box is special to me,
No doubt does it bring back happy memories.
