r-b,
Yes, I was just pointing out the perspective of the older sibling.
Of course, it’s not a simple matter, and each case must be evaluated separately.
I know a family in which the older sister met a young man but felt he wasn’t for her, so she suggested him for her sister. They are now married, but the older sister is still single several tears later.
I know of a different story in which the younger brother married before his older sister, who refused to speak to him until the day she died (a spinster).
Another story I’m familiar with involved two brothers. The younger one was told that he does not have to wait, but he chose to, regardless. The older one finally got engaged, and two months later, the younger one found his bashert.
I could go on, but my point is that it’s a complex issue, and one never knows how much pain could be caused to either party/
