###"I have something I'd like you to look at" This one looks more like procedural decomposition, TwitterHandle#valid? is a function operating on a data structure (string). the target does not "know" anything other than what is supplied as its argument.

validator = TwitterHandleValidator.new
 
TwitterHandleValidator.valid? "ben-biddington"

"Can I ask you a question?"

supplied with a true object, I can ask it questions.

handle.valid?

Can I introduce you to someone?

First I have to create a person to ask. Other than that, the same as the previous example.

text = "ben-biddington"

handle = TwitterHandle.new(text)

handle.valid?
