A problem (or two)

Do you ever feel like when you've solved one problem, another one appears (or maybe even TWO)?  Yeah, me too.  I mean, "me TWO."  Oh, never mind.  I'm just feeling a bit frustrated.  I think I'll go read a book.  Now, which book shall I read?  This one or that one?  Hmmm.  Hey, this is the kind of problem I prefer!
