It's high time we introduce another data type, namely, booleans. They're rather simple because they come in just two flavors: true and false.

How do we differentiate them from strings and integers?

Yup! We create booleans without quotation marks. That's how Ruby knows to evaluate them as booleans.

Psst: did you know that booleans are objects as well?

Wouldn't that make my_boolean a string?
