By overhearing my mom talk about me when she thought I wasn't home, and I've been thinking about it every day since.
Last year I came home early from work and didn't really make any noise coming in. My mom was in the kitchen on the phone, and I was just about to say something when I heard her say my name. I stopped and listened. She was talking to my aunt about me, saying how I had been struggling and how she watches me sometimes when I do not notice, just praying I am okay. Then she said she wished I knew how proud she was of me because she did not think I actually realized it. Hearing that completely caught me off guard. I stood in the hallway for five minutes and then quietly walked back outside to sit on the front steps. I ended up crying for a long time, the kind of crying where you are so overwhelmed you cannot even make a sound. My mom and I have never been the type to talk about our emotions. We usually show we care through small actions or making food for each other. I never told her I heard that conversation, but knowing how she feels has changed things for me. I carry myself a little differently now.
TL;DR - came home early, overheard my mom telling my aunt how proud she is of me when she thought I wasn't there. Haven't been the same since 💀
