I need your opinions!

I got friended on FB by two of Laura's daycare teachers.

I don't know what to do!  Do I friend them?  The young women who care for my daughter week in and week out?  Do I expose them to a more intimate view of Laura's life?  Do I expose myself to a more intimate view of their lives?  Do I want to know what they do on the weekends when they are not wiping snot and changing diapers?

Or is it a good thing for me to be more friendly with Laura's teachers?  Are they friending some of the other moms in the class?  Is this a way for me to reach out to actual human beings, and perhaps become more involved? 

PLEASE weigh in!  I am seriously unsure whether to click "Accept" or "Ignore."  I need your advice!
