We've been invited to dh's cousin's 18th - big posh black tie do in a hotel (why she wants a bunch of old farts at her 18th is a whole 'nother thread - personally, I went to the pub with my mates when I was 18). We're not going - it's the other end of the country and our children are not invited so we would have to leave them here with my parents overnight (and if we ever did that it would be to do something we want to do )
Anyway - I feel we should get her a gift but I hardly know her (have met her twice at family weddings) so...any ideas? Is a gift voucher too impersonal (also begs the question of value - 'cos she'll know...)?
Help please!
