To wonder what's the difference between christening invitation and funeral invitation

[Johnny5isAlive]

DH plays football on Saturday afternoons.
We received a christening invitation from my side of the family for 1pm on a Saturday. I accepted on behalf of myself and DC but will think of a suitable excuse nearer the time for DHs decline.
Now very sadly a relative of an old friend of DHs has passed away. He wants to attend the funeral. It's on a Saturday.
I'm not going to ask him as I know it has no place on such a topic. However AIBU to inwardly think that's double standards. If you refuse miss a footy game for a christening then why not a funeral?
We're not religious at all if that makes any difference.
I'm happy to accept being told it's an unreasonable thought

Here in Ireland there is generally better craic at a funeral.

Yabu. A funeral is much more important than a christening because it is a sad event whereas a christening is a happy event. It is much more important to be there for your friends when they are grieving deeply than when they are celebrating and won't miss you anyway because they're so happy

I'd do exactly what your husband chose to do, decline a christening but go to a funeral. I don't agree with christenings on principle, but I obviously don't say that to the parents! I just politely decline. Being none-religious does make it a very boring day as well. A funeral is about remembrance and respect of a friend/family member's life, far, far different situation, absolutely not comparable in my opinion. You may not agree with the religious sentiment of a funeral, but you certainly know it's the last time you will 'be with' the person in question, it's a moment of saying goodbye and have some closure.

People are not invited to funerals.
