Hospitality is in essence the love of strangers. In life, there are three groups of people. The idiot is self centered and never thinks of the needs of anyone else except themselves. The ethnic fellow thinks of his community but is suspicious of anyone who isn't in their tribe, professional line or one who doesn't speak their language. The real deal is the CITIZEN. This fellow thinks beyond himself, beyond his ethnic community and focuses on the needs of others. A citizen is a good candidate for hospitality. Apart from that, we must also learn to love good people. If you're predisposed to attracting people who hurt you and use you all the time then reevaluate your choices. You can go for good people as you aim to be hospitable.
