I asked this question in a few other communities. I really loved all the answers people came up with and it made me really happy that people were able to see so many different things in this one picture. The person that was pretty much dead on with my interpretation (and again that doesn't mean this person is right, every answer was just as right, it's just that we had similar stories) was hedgegoth, who said:
the part that makes the biggest impression to me is that we only see one person, but we see the shadows of two - indicating that even if it appears that the person is alone, they have someone beside them always.
Exactly what I was thinking! That even when we are apart, the mere thought of a the other brings that person, in some ways, back to us. No matter what happens, if things get bad or if good things happen, we always have the support of the other person to carry with us.
Thank you everyone for your excellent feedback! It meant a lot to me :).
