Yeah I get what you are saying. When I was younger and I saw that on the card I was kind of shocked lol, but perhaps I’ve grown used to the idea. I guess because whenever you go to someones wedding you do give them some kind of gift, so why not money rather than spending the same on something they may not use. I once saw an invite which asked to donate to their chosen charity and I am drawn to the idea and might use it when I get married.
