ISFJ hands over a lovingly packed lunch. INTP's first words: "How long did this take?"
They'll see this match write-up. Your test answers stay with you.
These two
INTP × ISFJISFJ quietly looks after INTP's daily life, and INTP shows ISFJ angles they'd never considered, so you fascinate each other. But INTP is bad at saying thanks out loud, and ISFJ's effort starts to pass as a given. ISFJ stacks up silent disappointment while INTP assumes all is well — until one day INTP hears "I never said anything, but…"
To make it lastINTP, one spoken thank-you a day. ISFJ, don't stockpile — say it right away.
