Use Your Own Key
Siblings can be annoying roommates too, sometimes even more than strangers. This OP’s brother has a terrible habit of forgetting to take his keys whenever he heads out. So, every time he’s at the door, he just messages the OP asking her to open the front door.
Now, it’s totally okay if this happens once in a while but as you can see from the messages, it’s almost a daily affair. Frankly, we think she is also to blame because he just takes it for granted that she’s going to let him in no matter what. It’s a good thing that she finally asked him to bring his own key for once.
