The whole family - 5 of us - has been invited to a surprise silver wedding party. Organised the the couple's daughters. They are lovely people. Not quite 50. They have 4 children and a house overflowing with nic naks - some nice pictures and ornaments. But I sense money is tight now as he has had to take early retirement. I don't want to buy them anything ornamental. Want to treat them. Can afford up to £50. Any ideas would be welcomed.
