What’s the most ADHD thing you do ?

I’ll start: when I think, my thoughts interrupt themselves. I start thinking about something and I didn’t even finish my sentence in my head that I start a new sentence, then a new one and so one.

Also, I always find weird things in places they don’t belong at all and I have no idea how they got there (I mean obviously it was my doing but I don’t know what went through my head when I did so)
