I recently heard a music artist for the first time in a long time that brought me back to my childhood.

Awww, what fun.  That must have been so nostalgic for you!  I wish I was back in childhood again sometimes.

It sure was! I enjoy reliving the memories, things were often simpler and more carefree back then.

I saw a toy that they are bringing back from a couple decades ago when I was a kid and wow, it was so neat to see!
