Thanks, I did mine like this and wasn't sure about it.

Note that although this works, this is not best practice as a new copy of the bark method will be created for each instance, rather than sharing a single instance of the bark method via inheritance. No inheritance is being utilized here. So it results in unnecessary extra memory usage.

Ah yes, good catch. I was going for dense and elegant, and missed that case.

This one counts the string "True" along with the boolean True.
