An invertible integral of cousins

I was reading over Salim's shoulder today -- I like looking at his screen while he is reading email. Some of the comics he reads online are pretty funny; some of them are sentimental; most of them make no sense (or are about dogs. Yuck!).
Anna was talking about the cousins she saw at the market today, and I realised how much I miss my cousins in the sunny Mission now that they have moved to frat row in Brentwood.
