Most ADHD symptoms are things everyone can relate to, this one included . The difference is most people do some of those things occasionally, while ADHD people tend to do many of those things multiple times a day. For example in my case I have this so-called doorway effect multiple times a day, but I also lose track of what I'm talking about or forget words really often, lose my things all over the place, need to work with alarms and reminders to be remotely close to functional due to severe time blindness, etc.

Also a gentle reminder not to party poop - although you were pretty respectful and didn't downright downplay the symptoms, some people suffering from ADHD tend to get rightfully tired of these comments altogether.
