Nostalgia
What a weird feeling you are. You spring up whenever you want to, Like a happy child, unpredictable in many ways.
A picture for example, One of your favorite tricks. But pictures are a bit like dreams, You forget some things.
Oh nostalgia how sickening you are. So sweet yet bitter, To reminisce upon.
Goodbye for now you say, Till we meet again. Nostalgia, my childhood friend.
