Elite,
My mom did that too. Sooo Embarassing watching everyone looking around for the one person called on the loudspeaker.
My mom especially told the neighbors when she was looking for me. So it got around the whole neighborhood that my momma said come home.
I had lil ol ladies coming out talking about...you know your momma wants you...I'd run all the way home and she'd say...go get me some ice from the freezer.
