I miscalculated bus times and ended up at the bus stop with twenty minutes to spare. So, I went and bought chocolate anyway, and stored it in my bag.
We had a great time together and then her brother drove us back over to my house. On the way I asked her if she regretted telling me not to bring chocolate. She said "No... well, yes..." So I gave her the chocolate with the admission that I'd brought some in case she changed her mind. This provoked delighted squeals.
I am terming this concept "eleventh hour chocolate," but not because it was between 11pm and midnight.
