My neighbor Steve went food shopping.
Is there a reason you wanted me to know about Steve?
I hate Steve. He is always eating all the food for himself.
Keeping a tab on what your neighbors are doing and eating can be seen as stalking. If he's paying for his food then he is entitled to eat all of it.
He's a bad person who always takes food out of my house.
If someone is stealing from you then you should report it. Although its good to be respectful of a neighbor, they crossed a line by stealing from you. Reporting them so that they're dealt with by proper authorities might make your neighborhood a little safer as well.
