My sister has bought ds a fully-equipped aquarium, with a voucher for fish, for his birthday. I can't believe she's unaware of how I feel about fish. Even typing this makes me feel uncomfortable. It's more than dislike, it's phobic.
I've explained to the dcs that we won't be buying fish for the aquarium, but will look into whether it's suitable for terrapins or frogs.
But I'm furious at my sister, and can't believe that my parents let her get away with it either!
