... "we are living in mama's cereal world.. and I am mama's cereal girl".... sounded good to me. I loved cereal.
When my big sister kindly pointed out to me that it was "material girl"... I thought she was one of those ladies at the fabric counter measuring out yards of material... I didn't like that as much.
