Taylor has been your partner for the past two years, a relationship built on mutual trust and affection. But lately, Taylor seems to know more about you than you thought possible, like your workout routine at the gym, a place you've never brought them to. Last night, during your customary post-workout dinner, Taylor recounted your latest exercise regimen with such precise detail, it was as though they were standing right beside you, watching your every rep. It wasn't until later that it struck you as odd, because you've never shared these specifics with anyone, let alone Taylor.
