l guess it would depend on why you’re telling me. Are you telling me this after you’ve worked my nerves and I’ve lost my temper over something you’ve done? Or are you telling me pre-emptively, before you’ve actually done anything?
If the former, I’d probably have a negative reaction. I don’t like that I’m like this, but I don’t like excuses. “Sorry if I acted like a jerk in the meeting, but I’ve got ADHD! Forgive me!” just sounds like excuse-making to my no-nonsense ear.
However, if it’s the latter, then I’d have more respect. If you told me something like, “If I am a little scatter-brained in the meeting, please be patient. I have an attention deficient disorder, and I really struggle sometimes”, you would at least prepare me so that I DON’T get annoyed. It’s kinda too late to make things better once I’m already annoyed.
I have a coworker I suspect is on the ADHD spectrum. Even knowing that he can’t help himself doesn’t change the fact that often he is very irritating. I’ve intentionally not invited him to a couple of meetings because he is notorious for derailing discussions and being the hyper, blabbermouth class clown. However, he’s a very smart guy, and he’s very good at what he does. The fact that he sometimes bugs the shit out of me doesn’t take away from the value he adds to the team. It just means I have to be extra patient with him.
