You may have seen this before, but I think it sheds some light on the nuances that words can make…

You see a gorgeous girl at a party. You went up to her and say “I am very rich. Marry me”.
That’s DIRECT MARKETING

You are at a party with a bunch of friends and see a gorgeous girl. One of your friends goes up to her and pointing at you says, “He is very rich. Marry him”.
That’s ADVERTISING

You see a gorgeous girl at a party. You go up to her and get her telephone number. The next day you called her and say, “Hi, I am very rich. Marry me”.
That’s TELEMARKETING.

You are at a party and see a beautiful girl. You get up and straighten your tie, you walk up to her and pour her a drink. You open the door for her, pick up her bag after she drops it, offer her a ride, and then say, ‘By the way, I’m very rich. Will you marry me?’.
That’s PUBLIC RELATIONS.

You are at a party and see a gorgeous girl. She walks up to you and says, “You are very rich”.
That’s BRAND RECOGNITION.

You see a gorgeous girl at a party. You go up to her and say, “I am very rich. Marry me”.
She gives you a nice hard slap on your face.
That’s CUSTOMER FEEDBACK.
