Mastering the skill of Self Portraits

I wonder how old a kid has to be before they get the concept of taking your own picture together? I was trying to get a picture of me and my niece Samantha but she just didn't get it. The more I tried the worse it got. She better learn this skill if she ever plans on going anywhere with less than three people.

Then this happened and I decided I must have severe ADD because even though I was taking my own picture, somehow in that fraction of a second between pressing the button and the picture taking I was distracted.

It wasn't even something big or startling that got my attention, I just got distracted. I guess I shouldn't give Samantha a hard time till I can master taking my own picture first. Simon didn't do much better but at least he wasn't trying to grab the camera.
