This is one of those stories that may not make a lot of sense. Unless you're me or my friend Ruth. We would often cook together in uni and once when we were going back to our rooms from the kitchen with our nice clean washing up, she thought aloud: "This is a really good bowl...you can use it for soup and cereal..." This made me stop and reply "As opposed to all your single purpose soup or cereal bowls".
We both laughed for ages and even though this was three years ago, it's become a bit of a catchphrase that we work into conversation whenever possible. I think maybe you had to be there.
So here's my story!
P.S. Apparently what she meant to say was that it was good for cooking in (ie soup) or eating from (cereal). Hurrah for pyrex!
