A book club, really?

So the other day I received an invitation from my friend/school librarian...there was a meeting for a new staff book club during lunch...my curiosity was piqued as my first reaction was that this would provide me with an adult with which to have a conversation on a campus that is incredibly disaggregated and lacks the group/staff cohesion and team spirit that my last school did.
In any case, I showed up along with about 10 other teachers and we discussed what books would make for a great discussion, but that wasn't incredibly "heavy". It dawned on my as we were discussing that I hadn't read a REAL adult book in quite some time..In fact, I realized that my only contributions would be suggestions related to children's books I read during our bedtime routine, the daily newspaper and an occasional People magazine. Later as I talked to my mom and dad she commented that they had both laughed initially at my crazy inclination to take on yet another obligation...after all, I work full time (as in 6:30-3:30 +), am now working out in the AM (as in 5-6 AM) and am also a full time mom with endless triumphs and tragedies...was she right?
I have come to realize that it is a part of who I am to bite off more than I can chew....join one too many committees, attend one to many meetings, say "yes" to one too many people, the list goes on. HOWEVER, when I sat down and thought about it, most of my day is spent DOING things for OTHER people. Whether it is getting lunches prepared (some of the time, I won't steal Steve's thunder), answering my students demands (all saying "miss" at the same time, needing me for some kind of reassurance or troubleshooting), answering emails from other people, picking up my kids, dinner, my day is about everyone else but me. So is a book club going to take more time that I don't necessarily have? is it a bit ambitious? of course, but it is for ME. It gives me time to talk with other adults and attempt to move beyond Dr. Seuss and David Shannon books ( ala bedtime routines). The club is more about being with people and less about what I actually read.
Now, I am off to read. :)
