In our custom, apparently , the thali is melted and made into a ring for the eldest son - kinda symbolic.
The ring suggests they are married/ engaged. If the person (man or woman) is ready to start dating, an engagement/ wedding ring would be confusing for the potential dates. I have seen people wearing their rings on the right hand instead of left so they could be asked out. (Germans (most Europeans?) wear the wedding band on right hand ring finger. I have a friend who wore a band on left hand to avoid interpreted as married but he was in the USA where he was frequently assumed married because of the band on left hand. He eventually took it off) Because it is not forced. I take off my wedding ring if it's too tight but my husband has never taken it off in 13 years. He is not forced to wear it, it's a choice. Don't think that was the point of this post. No one is attacking traditions.
