Just as it says in the title really.
My DH has a significantly younger relative who is getting married this summer. We have just received an invitation to the wedding, written entirely in Welsh. Neither DH or I speak Welsh and the bride and groom are well aware of this.
I am totally cool with somebody who grew up in a Welsh first language family wanting to celebrate their wedding in their language. However I can't help feeling it is a bit rude to send out invitations in a language many guests can't understand without even a short note in a mutually spoken language.
AIBU?
