To the Left To the Left

Its a song by Beyonce, written by Neyo. Do you know the inspiration for this song? I heard this on radio (told by Class 95 deejay Yasminne Cheng). This is what i roughly remember.  Neyo is telling a story about his aunt. She’s rich. Made tons of money. She has a useless bum boyfriend whom she dotes on him. She bought him lots of stuff. He also got some stuff as well. Apparently one day, she found out he was cheating on her all this while. So she put all the things that he bought for her into a box and when he came asking for his things, she said your things are all in the box to the left.
