Mr. Postman

I went to the post office yesterday to get postcard stamps. While the lady was very friendly and even complimented my super cute purse from Target, she said they had no post card stamps....
Seriously, you are the post office. How do you not have stamps. I'm just saying. Do they know what a whip it is to take a chatty 15 month old into the post office that is more quiet than the library or church and wait patiently in line shoving juice and cheerios on said 15 month old only to be told they don't have stamps... Good grief!
