There should be a place/set day for a certain party like a last day of summer party. Birthdays don't need to be big and for official holidays there should be a place for it. The holidays are from any country and everyone should go to the party if possible. If the host wishes for certain people to go then there is an invitation. I don't know if this will or should happen in the opinion of the staff but it's just a thing I think we should do.
