wierd habit

I have to laugh when I read this because I never realized it was a habit until I stopped to think about it. I actually do open the fridge door out of a habit. I will open it and look inside the fridge for a second and then not even get anything out and then close it. And I will do this throughout the say sometimes and each time I never get anything out of the fridge. And this can be when I'm home alone. LIke something honestly changed within 30 minutes, you know? It is weird. I don't know why I open it. I have food in it, but I never take food out. LOL!
