I've a close female friend whose gone through a very rough period in her life with divorce custody of the kids etc but over the last few months she has ballooned totally I mean u could carry a bag of coal home on her arse like from hot to not she brings up the subject of weight & what do I think I always change the subject but I'm too straightforward shes asking it more & more she'll ask me again tonight, how do I tell her nicely to lay off the swiss rolls?
