મુખમેં મીઠા મીટત નહીં, દુઃખમેં રહેવે દુર;

mukhamēṁ mīṭhā mīṭata nahīṁ, duḥkhamēṁ rahēvē dura;

Literally: Sweet of mouth, never ceasing to flatter, but staying far away in times of trouble;
What it means: Said of fair-weather friends who are full of sweet words but completely abandon you when you face adversity.
