Constant.
A decade and more of: uncountable tales, serious fights, embarrassing conversations, crying phonecalls, laughter filled outings, plenty of cakes, chais, thousands of selfies, crashing marine drive, mumbai locals, pani puri hauls, makeup tutorials gone right, makeup tutorials gone wrong, perfume hoarding, writing notes, writing letters, emotional airport drops, truck loads of gifts, bitching, gossiping, going gaga over Bollywood, knowing dark secrets, knowing funny secrets, loving, healing, disagreeing, making fun of xyz, heartfelt apologies, doing the dishes on Christmas nights, gobbling on mummy's pulav, gujju jokes, gujju bad words, bird watching, hunting for mehndi waalis, loving ranveer singh, loving music, sharing insecurities, building each other up, growing, evolving, unfinished ... And that's what you get from a constant.
