Hi Tia, Ruby doesn't support multiple inheritance but it supports what is called a mixin module or simply a mixin. Please reference "Programming Ruby" pages 118 - 120.

Good luck,

The point is, you're trying to inherit from two parents, which Ruby doesn't support. The way around this -- in Ruby -- is, as Conrad said, to use a module in which the methods you want are defined and then mix this in.
