And is that even OK?
Someone I worked with a long time ago is having a wedding party. She's much, much younger than me, but we've kept in touch through Facebook. It's been lovely seeing her reach her life and career goals.
She's had a shit time in the last year. New DH was diagnosed with leukaemia just about a week after announcing engagement, but they dug in and got on with treatment, always cheerful on the outside and thankfully he's OK. They had a much smaller wedding than anticipated, whilst he was still having treatment and now for the big wedding/all clear party.
She's invited me, which is lovely of her, but unfortunately I can't go. I'd love to sent them something though. The venue is a couple of hours away from us, so I can't drop it I on the day, but do you think I could send it to them? Maybe call ahead at the venue and tell them?
That'll be OK, won't it?
Oh and what do I send. Ideas please! 
. Not massive budget. It's just a token acknowledgment.
