Use to Remember

I use to believe in everything someone told me
I use to have a collection of stuff animals and rocks
I use to have so much energy I didn't ever want to go to bed

I remember sliding down hills acting like they were roller coasters
I remember every activity I did, it wasn't ever about winning but having fun
I remember those days where I could simply eat whatever without worrying about calories

I use to do those things
I remember doing all of those things
But I guess every small kid has to grow up sometime
