Haha! This made me laugh! I can imagine that you had fun capturing them. The middle one is more serious, but I have a feeling that the other 2 saw you taking their picture and just had to smile...
@ingrid01 Teehee I think you might be right. I had previously taken a photo that looked too posed so I waited a little while until they got more involved then captured this- however they knew I was still lurking!
