What do you learn at church?

So my kids have had to watch a lot of tv while I have been packing. One show they have watched a bunch is Alvin and the chipmunks. Tonight I was reading to the kids and they asked what we were going to do tomorrow. I responded "we are going to church" then Charlotte said "what do we learn about at church?" and I said "I don't know, what do you learn about?" to which she responded "hippies" I think that Alvin will need to be put away for awhile because they talk about how their parents were hippies and live on a commune.
