hi Caron,
I'm glad you're encouraging him to do the PaD project! He certainly has talent!
I thought for a while I was the youngest PADer (I'm 19) but your son beats me by a comfortable margin.
So I was 15 not long ago and I'll be honest with you. It's a great idea, and I do hope you post up those nouns when you get them! As good as it is, though, at 15 I would resent my mother trying to tell me what to shoot. Photography is self-expression, and by suggesting ideas, he may feel like you're trying to run his life.
On the other hand, I don't know what kind of relationship you two share. If it were me, I would take the ideas and do the requested photos, more for the satisfaction of my mother and her friends (who, I'm sure, would be anxious to see the result!) than for personal satisfaction. He might ignore the ideas or happily agree to do the photos, feigning embarassment by rolling his eyes
One of the best parts of my day today was taking my camera and walking up to the neighborhood park - alone - to look for today's photo. I think my mom finally realized how individual I am compared to others - photography isn't much of a social activity! As a mother, I'd encourage you to observe how he treats the photo-a-day project. Would he rather do it alone or with other people around? What kinds of photos does he take? What does he say when others ask him about photography and the PAD? I think photography could be a vehicle for growth and understanding in your relationship with Greg.
It's a difficult balance for my own mother, and perhaps for you too. My mom realizes how much photography means to me, so naturally, she wants to show interest and be a part of it. At the same time, she's learned, with noticable sorrow, that behind the camera lies my haven from the rest of the world. I don't know if the same will hold true for you.
Well this response has gotten to be a short essay. Of course, take it with a grain of salt, these are only my opinions.
Cheers,
wes
