Dear Sales Guy from Pictage:

First of all, I am not your girlfriend, you don't have to call me everyday.
Secondly, I am not your mother, and consequently don't need an update about your kids.
Third, I am not a friend, and don't need to chit-chat about the weather when you call.
Fourth, and this is the most important, I am not an interested customer, as I believe I said to you in our first conversation.

Please delete my number from your base of clients, and delete me from your life. Thank You.

Bothered to the point of being creeped out,
Me.
