Reply To: IY"H by you

When I get sincere brachos from kallahs I really appreciate it. In fact when the kallahs are my friends I go over to them and say I’ll take a bracha from the kallah please. I belive I have heard that a chosson and kallah have a special power of brochos or tefillas on their wedding. What drives me up a wall is when random people feel that saying the IY”H by you is the appropriate thing to tell any single that they sort of kind of know at weddings.
