When at their most evil, siblings can push all your buttons, narc on you to your parents, and reveal your most embarrassing moments to anyone who will listen. They can function as living, breathing manifestations of every pet peeve you've had, and they'll fully do it on purpose to get a rise out of you.

However, when their shadow side dissipates, siblings can also be some of the most ride-or-die friends imaginable. They already have an acute understanding of the cross you've had to bear growing up, so when their powers are used for good, it can be a blessing.

The Twitter user AnnieDaGrannie recently experienced the sweeter side of her 10-year-old brother during a crying spell in the bathroom, and shared the anecdote with her followers.

"So I locked myself in the bathroom bawling my eyes out...and next thing I know my 10-year-old brother slides these notes under the door...I don't deserve him," she wrote.

The notes were both lovingly and urgently scrawled on office paper and slipped under the door to comfort Annie.

The first one read:

"Ani it's okay, when she will come she will realize that she made you sad and she will apologize. Everything is going to be okay, if you're going to be thinking about it, it's going to make you sadder. Okay?"

The second note urged her to come out so they could do something to cheer her up.

"Come out so we could do something together fun and your mood will get better, okay?"

The interaction somehow became even more wholesome when Annie relocated to her room to process her feelings, and her younger brother made her a DIY package to cheer her up.

This is precious. I remember when my little brothers would try to cheer me up when I was depressed about something. This is just so wholesome, I love it 💚.

The holidays can be a deeply stressful time and it's easy to focus on all of the traits that make you want to strangle your family members. So, it's refreshing to see such wholesome displays of care.
