Be real boys!  The landlord daughter does not want to hang out with the tenants of her dad's.
Anyone who has been a landlord  knows that it is very unwise to become buddies with the
tenants.  Best to keep that arm's length relationship.  It's a business agreement after all.  The
sole reason for being a landlord is to benefit financially and it's best to keep emotions out of
the equation.  
Besides this, we do not all like to socialize with our neighbours.  One needs not be rude but
there is no reason why one has to become chummy with the guys next door either.  Polite is
a good way of being.
