I went to my first parent-teacher conference yesterday. Shanna is doing well, just starting to make some friends at school, and is generally exactly who we thought she was :-)
I got to shoo a snake out of our bathroom with the aid of a broom and some cardboard the other day. Hard for me to be sure, but the back patterns looked a lot like an Eastern Garter Snake, according to Google Image Search. Certainly I'd be surprised if it were anything venomous. There are only a few of those in the states, and the ones in CA are quite distinctive. We think it just slithered in when we had the front door open.
