Father Giving Away His Daughter
"While my father did walk me down the aisle at my first wedding, there was no giving me away. My father didn’t own me and didn’t make decisions about who got to marry me. My parents weren’t invited to my second wedding, something my mom was salty about for a while. But hey, I love my daughter more than I love her and my daughter went to school that day. It was a very simple civil service and the only reason there were any other people there was because we needed witnesses."
Wedding Gifts
"I won't solicit or take wedding gifts. There's no point in people giving me money for getting married. I believe that anyone daring to get married should bear full responsibility for it. I know this sounds controversial but that's how I see it. If one can't cover wedding expenses, how will they cover the costs of sustaining a family (which are much more expensive)? I don't want to bother others with my choices. I'd rather be given money when I get sick (which isn't a choice)."
Why? Because they don't want to follow every standard traditional thing?
If someone tells me that they don't understand some tradition a take them as an illiterate person. You don't need to follow, but understand? Just research it.
You can choose what you want.
