Can you help me with a good song name?

I've decided to write a song for my best friend, Nereida. She's like a little sister to me and I love her dearly. I need a good way to wrap all of it up and put it in a song that she'll understand. (Meaning nothing with big words! xD) I think, if someone can help me come up with a good song name, then I can figure out the rest, but I can't do it all on my own... Since it's summer break and everything, my creativity unit in my brain decided to shut down for a while, so I need some help! Thanks in advance.
