How many times is it appropriate to say "What?" before you just nod and smile because you still didn't hear what they said?

We went to the zoo for Cormac’s 2nd birthday today. Aside from the fact that we spent the day trying to breath air as thick as pudding and sweating so much we were all drenched before the dolphins tried to splash us, we had a great time. Of course I took my camera and took pics of Aidric and his nephew. The two boys had to stick their heads through every photo board in the zoo. They were turtles, fish, snails, frogs, water drops......well you get it. I took some movies of the stupid dolphin show and more photos of the boys with Matt on a giant bronze gorilla. Wonderful memories all fully documented....... I downloaded them to my computer and every f****ng one of them is blurry. I hate the auto focus feature because it flattens my pictures, they have no depth, but I’m so freaking blind even with my glasses on that I can’t manually focus either. Totally sucks!! hmmm....maybe I’m so blind that I only think the pictures are blurry as I look at them on my computer screen.......Hey, it could happen......
