actually most desis cant smile, walk around a mall and most off them walk around looking like they are there as a punishment. I think its somethign cultural.
many desi family portraits that I see are like american gothic or portraits of victorian era ppl, or even some of those old wild west pics that you see.
That is good that desi does not smile at desi. There will be tons of street fights if a desi smiles at other desi Starting with any one of the following opening sentences.
"Abay O-A toh maree biwi/bahan/baitee ko chair raha hay."
"Taree ghar main maan behnain nahee hain kia."
"Abay O-A bhawais hay kia , dosree taraf ko dekh."
"Abay daant bund kar warna bat-tee-see torh kay hath pay rakh doon ga"
So let the desi be desi. They can smile at goray and gorian but not at other desi.
