My partner and I are getting legally married after more than 25 years together. Since we are not starting out, we asked people, through the wedding web site, to donate to our favorite charity in lieu of a gift. The charity is for animal rescue.
Someone who is coming to my wedding texted me to say that by us asking for a donation to a charity instead of registering, we are saying that it is OK for them not to give anything since if a couple is registered, it is mandatory for guests to give something and we don't have a registry.
I'm not going to strongarm any guests into donating, but was wondering etiquette-wise, if my friend is right.
