That my mom is dead. I'm not old enough for people to really consider that that stage of life might have happened to me yet.

Also, that I'm hard of hearing. I'm in my early 30s, speak well, and don't look disabled. It's honestly like a superpower how fast people forget when I tell them I'm a lip reader or am (or am not) wearing hearing aids. Sometimes them speaking louder and to my face lasts a whole 2 sentences.
