A: if the lighting is poor you aren't gonna see much anyway.

B: this one depends. If once you're reading, nothing will distract you, you're fine. If you're easily distracted, you're gonna have trouble
C: there's always the chance you'll drop the book, unless you have that detachable shelf thingie I've seen around that the book is sitting on
D: well, it's socially rude, but otherwise is much like the football game, just more music and less crowd noise. Weddings are boring tho, especially if you are in it. I was a bridesmaid at my sister's, it was boring to be standing up there the whole time
Summary: depends on the person and details
