You lot will love this.
Relative, who I haven't seen for years and whose fiancée we've never met has sent a wedding invitation with tacky poem demanding suggesting money instead of a gift. And they got my name wrong (I have kept my maiden name and been married over 25 years).
Even if we don't go (and it will cause some family strife if we don't) my ailing dad expects that we'll send them money.
How much would you send? We're not millionaires, but not short of money either.
Mu judgement is somewhat affected by the fact that I have twice in recent years donated to couples asking for cash and am still waiting for an acknowledgement, let alone a 'thank you' from either couple.
