Learning to read between the lines

So, DH and I haven't officially begun the process and came into this with an open idea as to age of children we would be open to. While we'd like to stick to preteens, we're ok with younger teens too, and maybe even older teens depending on the kid(s). Originally, I had only considered adopting ONE child. DH suggested that we might miss out on some great kids if we didn't consider sibs. So, knowing we might only find a 2 bedroom home, I decided to be open to a sib set of two. I prefer boys, Dh is ok with either. When DH suggested considering a sib group, I decided to look at photo listings to help me think about this. This is when I started thinking the photolistings were giving clues to what types of behaviour to expect as well as history. So, if you read (this is not verbatium) something like "boys would like a home where kids are important, and the parents follow through on promises and are consistant" (sib set, two boys between about 9 and 15) what do you read between the lines? I think I see some things there but don't want to post until I read others thoughts. One thing I've learned is that we might need to be able to interprete what we're being told because the CW might not, or at worst, might "forget" to mention things that somehow were 'left out" of the case file... So I'm trying to work on that skill, although in the end it's just an educated guess.
