You were going to get a flat anyway, getting it at home was lucky!
In time you will have extra patch kids, levers, etc. Here is an idea what to do with them. I keep a patch kit, tire levers and an old frame pump in my truck. I have stopped many times over the years, to help stranded riders. I remember once helping a guy that had two extra tubes and had three flats. He was from out of town, had no patch kit and was in a area with no cell coverage. He couldn't thank me enough.
I recently had a flat and was fixing it. I had a young couple who stopped and offered thier help. It was nice to know that if I needed it, they were there.
