Would it be proper to ask guests to contribute toward the party celebration (food and drink) and a gift for my parents?
A. This is very much down to your family’s etiquette. i.e. if these types of celebrations occur in your family circle then there should be no problem in doing this. Contributing to a gift can be a very good way of ensuring that a suitable gift is given that your parents would like, this especially if you have a good idea of something they would both very much like.
