Saw a guy at the T station this morning wearing the exact same Red Sox cap my dad's had since '98 — faded navy, bent brim, grease stain above the bill from changing his own oil. For a second I just froze, throat tight, thinking he'd turn around and it'd *be* him, even though he's been gone three years now. How do you know when something's just a coincidence versus your brain trying to tell you something?
