Mate I've forgotten the concept of eating food, I've misplaced my phone that I was holding 30 seconds ago, I've not been able to recall every card in any of my magic the gathering decks from memory ever since I started playing about 10 years ago.

I've forgotten what I was talking about mid sentence because I had to get a sip of water. You can forget about anything with ADHD, just different people remember things differently. I can recall my partner's favorite colors and hobbies, I can barely recall my own favorite media I saw.
