How does this picture make you feel? Would you feel more comfortable if was cut down the middle and was two different pictures? Maybe it does not bother you at all.
I think it encapsulates a lot. When I first looked at this I felt uncomfortable for the couple on the right and thought that perhaps the couple on the left should show more respect. But then I thought perhaps one of the (or both) of the couple on the right wished they could do the same as the couple to left who are just showing affection to each other (she is cradling his head). Perhaps the right hand couple are not even passing judgment, just watching with a curious nature, perhaps they think it is a nice thing to see - but feel no difference. Perhaps the couple to left are just 'seeing' each other on just a physical level, perhaps they will be together to death part and love each other immensely. I came to the conclusion that you really cannot judge from what you see with your eyes sometimes and your emotions and opinions could quite easily get it wrong and taint reality.
You can't judge a book by it's cover. I picture may speak a thousand words, but will it be the truth that you hear?
I am sure it will create an interesting reaction in you, just step back afterwards and think about how you feel or what conclusion you come to in the first few seconds and then think again........
