silhouettes and a revelation

I am constantly being told how similar my boys look.  They are often asked if they are twins.  Here is the thing...they are three years apart, and their personalities are night and day, so I just don't see it.  Do you get that too, where you see someone based on their personality, rather than their actual appearance?  I never even thought about it until a few people started pointing out that I see people differently than most.  Hmm.
Anyways, what I couldn't see in person shows up on paper...

We needed to make some silhouettes for a secret project the boys are working on.  Now, I see it!
Not twins, mind you, but I see the similarities.  N is on the left and S is on the right.

Have a nice day.
