The on-time departure
You both arrive five minutes early, and neither of you is surprised.
They'll see this match write-up. Your test answers stay with you.
These two
INTJ × ISTJBoth responsible and plan-minded, things run like clockwork when you're together, and since neither of you is very expressive, there's no pressure. The difference: INTJ wants to try new methods, ISTJ prefers what's proven. Every "let's try it this way" from INTJ meets "the old way worked fine" from ISTJ, and you're both stubborn enough that this talk drags on.
To make it lastTrial the new way exactly once, then let the results decide.
Each on their own
You review your own feelings before acting on them, so things start slow. Once you're in, you remember every preference and plan dates months ahead. Just know that "I booked our trip" doesn't always land the same as "I like you" — say both.
The Record KeeperYou won't write poems, but you'll never forget an anniversary. You're slow to commit and very hard to shake once you do. A partner who never plans anything will test your patience.
