Modern Day Example
A modern day example of the Grangerfords taking Huck in is a familly taking a foregin exchange student into their home. Hosting a foregin exchange student in your own home is a very hospitable act and the Grangerfords do the same to Huck. This is also similar because meeting the family for the first time might be strange and weird, just like Huck with the Grangerfords when they got there guns ready before he walked in.
