Never be possessive. If a female friend lets on that she is going out with another man, be kind and understanding. If she says she would like to go out with the Dallas Cowboys, including the coaching staff, the same rule applies. Tell her: "Kath, you just go right ahead and do what you feel is right." Unless you actually care for her, in which case you must see to it that she has no male contact whatsoever.
