Arthur and Eames text quite a bit and Eames' mum is posh and terrifically droll. (found!)

Okay, so I may be conflating two stories here, but I don't think so. The only thing I can remember is that Arthur and Eames text quite a bit and at one point Arthur says something to the effect of, "stop texting me," and Eames replies, "No, shan't." Additionally, Eames' mother is really aristocratic and amusing and says things like, "You'd better have an exceptionally good reason for missing my birthday, otherwise you may expect your disinheritance papers in the post directly."

I don't remember anything other than those quotes, so if someone could help me out I'd be most grateful!
