Is this a medical condition?
i have a friend of mine who, ever since she was very young will (and still does)from the time she wakes up till the time she goes to bed-even getting up during the night to do this is eating.! And i'm not talking about grazing, either she literally DOES.NOT.STOP.
Examples:-1997 we were vacationing with her family and when we got to the hotel, even though everyone was told NO she makes a beeline for the mini-bar and tried to open it! There was a soda machine right down the hall she didn't want to pony up $.75 for a soda! She tried to grab the one i had in my hand i ended up punching her in the face and then spitting on her. i was so irritated!
2012-She was an exchange student in France not even a week into her stay with her host family, she was rummaging through their refrigerator at all hours! These people wised up really quick and put a padlock on the refrigerator. i would be completely mortified if i let that π in my house and she pulled that crap!
And because she's so much better than everyone else, she never apologized to her host family either verbally or through a letter.
Good people are always so sure they're right.
