Sgt. Impulsive

One thing that has been a constant struggle for me is that of being impulsive. It is a common thing associated with ADHD and for me is all too common. Poor Sara is often a victim of my impulsiveness.
Well on Thursday I went to pick up the house keys from sara at school due to me loosing them on a hiking trail, (another crazy Andy story), when I interrupted story time in her class. Well Sara gave me instructions of things to do before we could leave for our trip to Idaho. Well being the goofball I am I saluted her which got a rise from her class. Sara then looked at me with a slightly frustrated look and explained to me that her class was in trouble for no being respectful of adults and that what I was teaching them was counterproductive to that. Well Sara gave me some more instruction and in response before thinking I gave her a salute again. This was responded by one of her kids saluting her and saying, "Aye Aye Captain."
Sara scolded the student and gave me a look that would pierce the skin of the roughest Sailors soul. I knew I had blown it and the worst thing is I could give no explanation to why I did it. Sara had just told me why that wasn't helping and she has such a hard time with some of theses kids and the last thing she needs is her best friend making things worse. I still to this moment can't give an explanation for my actions.
I left her class texting her and begging for an apology. She said she really didn't care and I believed her mostly, but I think it hurt me more that I couldn't think of the my actions before I did it. This is actually a minor case I've had far worse consequences for my impulsiveness, but no matter how minor it is hard to put a finger on why I do such things.
