India, Aug. 6 -- Every friend group has one. That buddy who's holding the gang together with invisible labour. This is the friend who will take your calls at whatever time of the day, even when you only ring when you're annoyed and stuck in traffic. This is also the friend who hears someone say "Let's meet ya", picks the date, time and place that works for everyone, makes the reservation, does the Splitwise payment and lets the other person believe that the meet-up was their idea. It's the same person who remembers everyone's birthdays and reminds everyone else (and lets them add their names to what is never a group gift). And they're the ones who share advice, look over your final draft before you hit Send, and send you Zomato surprises ...
