He ain't heavy...

Just a casual shot I took the morning after the wedding. 
My sons, 3 years apart to the day, have  always been close although not always comfortably so. Bound together willy-nilly by their shared parentage they have often seemed to me like oil and vinegar, qualitatively different yet capable of forming a perfect emulsion.
Now that one has a partner welded on it will mean change for both and maybe there's a certain wistfulness as this new stage of life unfolds.
