SIL is currently visiting (not staying with us, thank heavens). She is usually abroad with her job in far away countries which suits DP & I as we have quite a strained relationship with her - at worst she is a selfish, opinionated, stubborn and rude cow but can be sweet as pie when she wants something - but I have always played the nicey nicey girlfriend to keep the peace as she is not here often.
She wants DP & me to join her & FIL for an early tea on Sunday at a very exclusive fish restaurant in town.
The main problem is I hate fish. The restaurant is very expensive and serves nothing else, not like the chain fish restaurants where they serve non-fish dishes, this is just fish, fish, and more fish (I have scoured the menu!). We would also have to find (and probably pay for) a sitter.
She is adamant she wants to go to this particular restaurant, which is fair enough on her part. Would I look a complete cow if I decline and just tell DP to go without me on the basis that I don't eat fish? I'm sure she will think I'm sulking about it but I don't mind DP going, I just don't see the point in me going.
