B"H I had the wonderful opportunity to help someone put in teffilelin today. A coach bus stopped outside my yeshiva about 20 minutes before shkiah and ask a friend if he had teffilin, he in turn asked me and I brought mine out. It seems he was driving a group of girls around all day and didn't have a chance to put on before be left (or maybe he left before sunrise, not sure. He was speaking blazing fast Hebrew I didn't catch everything he was saying).
