There was a time I used to forget things like mad. Tell me something this minute or ask me to inquire of a particular, I will totally forget. At that point in my life, it was mostly because of stress. I learned to take care of my mental health better and now I don't forget like that anymore.
With the way my dad loves his food, I doubt I would've had a chance to forget if I were in your shoes😂
It happens to me, too. Sometimes, I'd assure you of reminding you only to forget and that can be painful, especially when we'd disappointed someone.
