Growing up with siblings means sharing a lot—food, clothes, and sometimes even beds when you least expect it. Maybe your sister had a nightmare and sought comfort, or perhaps she just wanted to chat late at night and dozed off. In my experience, siblings have this unspoken bond where personal space becomes flexible during moments of vulnerability. It could also be something as simple as her room being too cold or her mattress uncomfortable that night.
Whatever the reason, it’s one of those quirky little things that make sibling relationships special. You might tease her about it later, but deep down, it’s a reminder of how close you two are. Next time, maybe keep a spare blanket handy—just in case.
