In a viral Reddit post shared on the Am I The A**hole group, which can be seen here, user u/diabetstashaiththrow explained his wife, 27, was diabetic and needed sweet snacks to keep her blood sugar up.

According to the Centers for Disease Control and Prevention, in 2018 there were some 34.2 million people in the U.S., roughly 10.5 percent of the population, who had diabetes.

The user added that his 32-year-old brother had stayed with them as he looked for another job, but was expressly told not to eat the snacks that were saved for his wife.

He revealed that the snacks had “vanished” one day and that the brother later admitted to taking them as a “prank.”

The Reddit user then added: “I told him that he cannot ever do that again and if that happens he won’t have access to the pantry and [that] he’s incredibly immature. I told him what happens if she doesn’t keep her blood sugar up. He apologized to her. We stocked up.

“A week later, gone again. I went straight to him, he said he ate them. I told him he’s now going to be buying his own groceries, he tried to plead and said he just had a ‘sweet tooth’ and that’s the only thing he could find.

“I gave him a final warning and said that if this happens again, he won’t be welcome here. I suggested he go to my parents’ house then, my wife said [s]he will just bring her stash into our room.

“We were good for about a month until my wife texted me while at work, understandably upset, and again, he took her whole thing. This time was it, told [him] he’s going to have to stay with our parents. Our parents welcomed him.”

But the Reddit user revealed that his family has started “blasting” him online and branded him a “horrible brother” for kicking him out and suggested that locks could be put on the bedrooms.

The man continued: “He is literally making our home unsafe. I don’t see why I have to childproof my house from a 32-year-old man. I gave him three strikes.”

Since the comment was shared on Tuesday, July 12, the post attracted more than 5,345 upvotes and hundreds of replies.

Most of those who commented on the post were outraged over the brother’s behavior and also slammed the user’s family for suggesting putting locks on the doors.

One Reddit user with 7,700 upvotes said: “NTA (not the ahole). Put a lock on your room? In your own house? F* that noise, your family is insane.

“Your brother is a God damn adult in their 30s and you gave them multiple warnings. Anyone siding with him should be cut off as well.”

Another added: “A lock pretty much says there’s no trust and if OP (original poster) had done that, no doubt would be blasted for not trusting their brother.”

While a third posted: “NTA. Your house, your rules and he violated those rules three times. He could live rent free but a 32-year-old man decided some free candy was more important.”
