I posted on the religion page a few days ago but haven't had any responses!
My lovely neighbours have invited me and the kids round to help celebrate their son's wedding. They are British Sikhs and reasonably observant as far as I know - they have a family shrine, the dad wears a turban etc. We aren't invited to the ceremony itself just the party at home after.
Is there any particular ettiquette I should be aware of? eg receiving lines, customary greetings etc? Also I don't want to go empty handed but am not sure what sort of gift would be acceptable?
Thanks very much!
