In "to kill a mockingbird", scout said "he ain't company, cal, he's just a cunningham." what does she mean by this statement and what was cal's response?

Scout means that since Walter is poor he shouldn't be treated as a "normal" guest would because he is, in her eyes, worth less in a way.  Cal takes Scout to the kitchen and scolds her, pretty much saying he's your guest and you better treat him with respect.  She gives Scout a little spanking too and sends her back to apologize.

Bis the answer hope this

They were both presidents.
