Why do Indian brides seldom smile on their wedding day?

i am indian too and i was very happy at my wedding and also sad to leave behind my family and pets but i had a new life waiting for me and that too with the man i love so much, it was a mixed emotion but i was never scared of my mom in law as you get what you give and even if she is not good my husband will always support me.so, i was at cloud number 9 and i had the perfect wedding with the person i love the most
