Some people create new rishta’s very comfortably … they feel it easy to call a stranger “bhai” “behn” " pupho " or any other traditional rishta’s …
Personally , I dont feel so comfortable creating zaberdasti ka rishta’s but do you think its a positive thing to be able to feel so close to others and addressing them with these special rishta’s ?
Well i have a habbit of calling everyone “bhai”, earlier it use to be either “bhai” or “yar” but had to get rid of the latter. However, just because you call someone “bhai” doesnt mean you are joding a rishta with them , for me its just a respectful way of addressing any male.
i use word "bhai jaan" when going to some shop in Pakistan or "bhayya" if the guy is younger than me. but this doesnt mean creating rishtay dari with them.
