My friend recently bought a new house and is having a Housewarming Party to celebrate. She has invited about 50 people and will be serving snacks and drinks on a Saturday evening. I always thought a Housewarming Party was a get-together that another person hosted for the owner of a new house. The invited guests bring gifts. An Open House is an event where the host or hostess invites guests for a casual reception at his or her new home and gifts are not expected. I think it is tacky for a person to host their own Housewarming Party. Is it just me? Do I have my ettiquette mixed up?
