Is it really that hard to smile?

I don't really ask the boys to pose or smile for me that often, but by the looks of it you would think it hurts to do it.



Why is it so hard to smile?



I tell funny jokes, pull all my tricks out for that one perfect smile.

Oh the pain of it all...





Seriously what does it take to get a real, natural smile.



Let me know when you figure it out.











These two pictures are not the same...





They're different.






Same smile :|
