<p>I am thinking more along the lines of having lunch with a student off campus.&nbsp; This type of behavior may raise a red flag.&nbsp; There is definitely a problem with students driving instructors' cars and visiting instructors' homes.&nbsp; I am somewhat torn about the personal mobile number and home phone; this type of behavior can really be innocent.&nbsp; It really depends upon the instructor as to how negative any type of behavior is.</p> <p>&nbsp;</p>
