My mom picking me up from elementary school and driving home. Laying on top of my couch while looking outside during the middle of summer and being young enough not to worry about anything except deciding what to do with that day. Sitting in my math class in middle school and looking outside as the weather was turning to fall. Having a planned friend that you would always meet up and walk to that certain class with. Or after school secretly hoping you’d see that one person before you went home for the day.
It’s not even the situation or the context, just that feeling you get. That comforting, warm feeling.
