સાસરે જતાં સૌને ભાવે, ને ઊમરે એણગતાં આંસુ આવે.

sāsarē jatāṁ saunē bhāvē, nē ūmarē ēṇagatāṁ āṁsu āvē.

Literally: Everyone likes going to the in-laws, but crossing the threshold brings tears.
What it means: Anticipating a major life transition feels pleasant until the actual moment of parting arrives.
