Why do Brides Cry?

Re: Why do Brides Cry?

I'd be crying internally; I don't think I'd be able to muster out physical tears but I'd probably squeeze the life out of my loved ones through hugs. It's HARD to cry in front of so many people not to mention a camera that's all zooming in on you and shiz.

What I want to know is why desi women (older ones I guess) have created such a stigma out of a bride not crying during rukhsati? What's it to them!?
