I did see your post earlier, but I had no idea how to respond to it. To me,
What you are requesting is kind of a hard category to fill. Alot of songs I
know aren't suitable for framing ;). You could always go with the standards of
" wind beneath my wings" or how about "you are my sunshine"or "wherever we go"
? It's hard to find a good song describing a solid relationship between
sisters as you know, it's too happy a topic. Perhaps if you searched for songs
focusing on the picture and what you both were doing in it, maybe it would be
easier to find the perfect song. Just a thought. I hope you are able to find
what you were looking for.
