Really? What was that about?

Tomorrow, we leave to go to Cornell for 3 days worth of GIS/GPS training. Due to poor planning on my part, we will be leaving from Brockport at 3PM or later, because I inadvertently scheduled journal training for 2PM. So, in order to feel less stressed about it, I decided to try and have everything ready and in the car tonight. I packed the suitcase, kept out my morning pills, and suggested that John do the same. He has two glucose meters, so I thought he could take his current one with, and leave his older one out to use tonight and in the morning. He disagreed with the idea, but gave it to me anyway. Then he freaked out about how I didn't trust him to manage his own healthcare, and how he manages his conditions better than I manage mine. I have no idea where this came from, or why he felt it necessary to humiliate me in front of Brandon, but there you have it.
