Nothing says "I'm a physics major" quite like using astronomical distances to measure the duration of your feelings. 2.5 light-years is approximately 14.7 trillion miles—enough time for her to read that text, roll her eyes into another galaxy, and hit block faster than a neutrino passes through matter. Pro tip: If you're going to be scientifically romantic, at least get the units right. Light-years measure distance, not time—though in this case, the distance between these two just became infinite.
