A picture is worth a thousand words
I take out the camera, frame a shot to my satisfaction, twiddle with the settings, set it on continuous shooting, and click and click and click. After a few dozen shots, A switches places with me. He shoots a single picture and says "ok. We're all done!"
And then I start to download pics. There are lots of pics of A and the kids. I take my time, screen out the not so nice ones, mail out the good ones to family and friends.
And then the inevitable question comes along. "Hey, why aren't you in any of the pics?"
Hmm... I was the one shooting. That's why I'm not in any of the pictures.
It's time for the second inevitable question. "I thought Arun said he shot a few pictures too." Oh well, since you asked for it, I send out a nice blurred image that could be anything from my family to the yeti family.
On the other hand, maybe this is a good sulking point.
"I take such nice pics of you, and you can't get a single good shot me!! Least you can do is get me a surprise gift that I'm sure to like!"
I can see the possibilities there.
