My first camera was a Kodak Instamatic 100 that had belonged to my grandmother, I don't really know when it was given to me, probably the late 70s. I, too, got in trouble for shooting (wasting) too much film on photos of "silly" things. I put a lot of film through that little camera on many family vacations and just around the house. When I finally broke it at the age of 14, we threw it away and I did not get another camera of my own until I went off to college and bought a Nikon SLR. I have a sentimental attachment for the Instamatic for no good reason. I bought another one, the same model, at a yard sale for a dollar some years back just to have it. My replacement came with a demonstration cartridge that was presumably intended for camera dealers to show how easy it was to load the camera!
